HF significantly influences the performance of Li-ion batteries, for example by impacting the formation of the solid electrolyte interphase at the anode and by affecting transition metal dissolution at the cathode. Additionally, HF complicates studying fundamental interfacial electrochemistry of Li-ion battery electrolytes, such as direct anion reduction, because it is electrocatalytically relatively unstable, resulting in LiF passivation layers. Methods to selectively remove ppm levels of HF from LiPF6-containing carbonate-based electrolytes are limited. We introduce and benchmark a simple yet efficient electrochemical in situ method to selectively remove ppm amounts of HF from LiPF6-containing carbonate-based electrolytes. The basic idea is the application of a suitable potential to a high surface-area metallic electrode upon which only HF reacts (electrocatalytically) while all other electrolyte components are unaffected under the respective conditions.","lang":"eng"}],"date_created":"2024-03-08T06:27:10Z","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"keyword":["Materials Chemistry","Electrochemistry","Surfaces","Coatings and Films","Condensed Matter Physics","Renewable Energy","Sustainability and the Environment","Electronic","Optical and Magnetic Materials"],"type":"journal_article","author":[{"last_name":"Ge","first_name":"Xiaokun","full_name":"Ge, Xiaokun"},{"full_name":"Huck, Marten","last_name":"Huck","first_name":"Marten"},{"full_name":"Kuhlmann, Andreas","first_name":"Andreas","last_name":"Kuhlmann"},{"full_name":"Tiemann, Michael","first_name":"Michael","last_name":"Tiemann","orcid":"0000-0003-1711-2722","id":"23547"},{"id":"11848","last_name":"Weinberger","first_name":"Christian","full_name":"Weinberger, Christian"},{"full_name":"Xu, Xiaodan","last_name":"Xu","first_name":"Xiaodan"},{"full_name":"Zhao, Zhenyu","last_name":"Zhao","first_name":"Zhenyu"},{"first_name":"Hans-Georg","last_name":"Steinrueck","full_name":"Steinrueck, Hans-Georg"}],"publication_identifier":{"issn":["0013-4651","1945-7111"]},"title":"Electrochemical Removal of HF from Carbonate-based LiPF6-containing Li-ion Battery Electrolytes","year":"2024","article_type":"original","intvolume":" 171","publication_status":"published","date_updated":"2024-03-25T17:01:09Z","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://dx.doi.org/10.1149/1945-7111/ad30d3","open_access":"1"}],"doi":"10.1149/1945-7111/ad30d3","citation":{"chicago":"Ge, Xiaokun, Marten Huck, Andreas Kuhlmann, Michael Tiemann, Christian Weinberger, Xiaodan Xu, Zhenyu Zhao, and Hans-Georg Steinrueck. “Electrochemical Removal of HF from Carbonate-Based LiPF6-Containing Li-Ion Battery Electrolytes.” Journal of The Electrochemical Society 171 (2024): 030552. https://doi.org/10.1149/1945-7111/ad30d3.","short":"X.

While semiconducting metal oxides such as In2O3 can monitor gas concentrations down to the ppm range, they often exhibit cross-sensitivity to other gases like H2O. In this study, we investigated whether cyclic optical illumination of a gas-sensitive In2O3 layer creates identifiable changes in a gas sensor´s electronic resistance that can be linked to H2 and H2O concentrations via machine learning. We exposed nanostructured In2O3 with a large surface area of 95 m2 g-1 to H2 concentrations (0-800 ppm) and relative humidity (0-70%) under cyclic activation utilizing blue light.

This is achieved by incorporating different linker molecules (L) into the structure, generating isoreticular frameworks. CPO-27, also named MOF-74, is a prototypical material for this approach, offering the potential to modify the size of its one-dimensional pore channels and the hydrophobicity of pore walls using various linker ligands during synthesis. Thermal activation of these materials yields accessible open metal sites (i.e., under-coordinated metal centers) at the pore walls, thus acting as strong primary binding sites for guest molecules, including water. We study the effect of the pore size and linker hydrophobicity within a series of Ni2+-based isoreticular frameworks (i.e., Ni2L, L = dhtp, dhip, dondc, bpp, bpm, tpp), analyzing their water sorption behavior and the water interactions in the confined pore space. For this purpose, we apply water vapor sorption analysis and Fourier transform infrared spectroscopy. In addition, defect degrees of all compounds are determined by thermogravimetric analysis and solution 1H nuclear magnetic resonance spectroscopy. We find that larger defect degrees affect the preferential sorption sites in Ni2dhtp, while no such indication is found for the other materials in our study. Instead, strong evidence is found for the formation of water bridges/chains between coordinating water molecules, as previously observed for hydrophobic porous carbons and mesoporous silica. This suggests similar sorption energies for additional water molecules in materials with larger pore sizes after saturation of the primary binding sites, resulting in more bulk-like water arrangements. Consequently, the sorption mechanism is driven by classical pore condensation through H-bonding anchor sites instead of sorption at discrete sites."}],"page":"1791","_id":"56947","publisher":"MDPI AG","user_id":"23547","volume":14,"status":"public","oa":"1","citation":{"ama":"Kloß M, Schäfers L, Zhao Z, Weinberger C, Egold H, Tiemann M.

It is therefore an ideal host material for small guest molecules, including water. This opens up numerous possible applications, such as proton conduction, humidity sensing, water harvesting, or adsorption‐driven heat pumps. For all of these applications, profound knowledge of the adsorption and desorption of water in the micropores is mandatory. The hydration and water structure in CPO‐27‐M (M = Zn or Cu) is investigated using water vapor sorption, Fourier transform infrared (FTIR) spectroscopy, density functional theory (DFT) calculations, and molecular dynamics simulation. In the pores of CPO‐27‐Zn, water binds as a ligand to the Zn center. Additional water molecules are stepwise incorporated at defined positions, forming a network of H‐bonds with the framework and with each other. In CPO‐27‐Cu, hydration proceeds by an entirely different mechanism. Here, water does not coordinate to the metal center, but only forms H‐bonds with the framework; pore filling occurs mostly in a single step, with the open metal site remaining unoccupied. Water in the pores forms clusters with extensive intra‐cluster H‐bonding.","lang":"eng"}],"date_created":"2024-09-06T07:07:17Z","type":"journal_article","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}]},{"date_created":"2023-06-12T07:42:09Z","type":"journal_article","keyword":["CO2 Adsorption","Cesium Acetate","Cesium Effect","Porous Carbons","Supercapacitor"],"citation":{"apa":"Li, J., Kossmann, J., Zeng, K., Zhang, K., Wang, B., Weinberger, C., Antonietti, M., Odziomek, M., & López‐Salas, N.

Here we use cesium acetate as the only precursor of oxo-carbons with large SSA of the order of 3000 m2 g−1, pore volume approaching 2 cm3 g−1, tunable oxygen contents, and yields of up to 15 %. We unravel the role of Cs+ as an efficient promoter of framework formation, templating and etching agent, while acetates act as carbon/oxygen sources of carbonaceous frameworks. The oxo-carbons show record-high CO2 uptake of 8.71 mmol g−1 and an ultimate specific capacitance of 313 F g−1 in the supercapacitor.

HTC of different saccharides is known to produce microspheres (MS) with mostly Gaussian size distribution, which are utilized as functional materials in various applications, both as pristine MS and as a precursor for hard carbon MS. Although the average size of the MS can be influenced by adjusting the process parameters, there is no reliable mechanism to affect their size distribution. Our results demonstrate that HTC of trehalose, in contrast to other saccharides, results in a distinctly bimodal sphere diameter distribution consisting of small spheres with diameters of (2.1 ± 0.2) μm and of large spheres with diameters of (10.4 ± 2.6) μm. Remarkably, after pyrolytic post-carbonization at 1000 °C the MS develop a multimodal pore size distribution with abundant macropores > 100 nm, mesopores > 10 nm and micropores < 2 nm, which were examined by small-angle X-ray scattering and visualized by charge-compensated helium ion microscopy. The bimodal size distribution and hierarchical porosity provide an extraordinary set of properties and potential variables for the tailored synthesis of hierarchical porous carbons, making trehalose-derived hard carbon MS a highly promising material for applications in catalysis, filtration, and energy storage devices.","lang":"eng"}],"issue":"21","publication":"RSC Advances","doi":"10.1039/d3ra01301d","main_file_link":[{"open_access":"1"}],"language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2023-05-12T07:18:51Z","intvolume":" 13","title":"Hard carbon microspheres with bimodal size distribution and hierarchical porosity via hydrothermal carbonization of trehalose","year":"2023","publication_identifier":{"issn":["2046-2069"]},"author":[{"full_name":"Wortmann, Martin","last_name":"Wortmann","first_name":"Martin"},{"full_name":"Keil, Waldemar","last_name":"Keil","first_name":"Waldemar"},{"full_name":"Diestelhorst, Elise","last_name":"Diestelhorst","first_name":"Elise"},{"full_name":"Westphal, Michael","first_name":"Michael","last_name":"Westphal"},{"full_name":"Haverkamp, René","first_name":"René","last_name":"Haverkamp"},{"first_name":"Bennet","last_name":"Brockhagen","full_name":"Brockhagen, Bennet"},{"full_name":"Biedinger, Jan","first_name":"Jan","last_name":"Biedinger"},{"full_name":"Bondzio, Laila","first_name":"Laila","last_name":"Bondzio"},{"first_name":"Christian","last_name":"Weinberger","full_name":"Weinberger, Christian","id":"11848"},{"first_name":"Dominik","last_name":"Baier","full_name":"Baier, Dominik"},{"last_name":"Tiemann","first_name":"Michael","orcid":"0000-0003-1711-2722","full_name":"Tiemann, Michael","id":"23547"},{"last_name":"Hütten","first_name":"Andreas","full_name":"Hütten, Andreas"},{"first_name":"Thomas","last_name":"Hellweg","full_name":"Hellweg, Thomas"},{"full_name":"Reiss, Günter","first_name":"Günter","last_name":"Reiss"},{"full_name":"Schmidt, Claudia","first_name":"Claudia","last_name":"Schmidt"},{"last_name":"Sattler","first_name":"Klaus","full_name":"Sattler, Klaus"},{"full_name":"Frese, Natalie","first_name":"Natalie","last_name":"Frese"}]},{"date_created":"2023-04-22T06:17:33Z","keyword":["General Chemistry","Catalysis"],"type":"journal_article","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"issue":"26","publication":"Angewandte Chemie International Edition","abstract":[{"text":"Faradaic reactions including charge transfer are often accompanied with diffusion limitation inside the bulk.

The redox mechanism is investigated by means of X-ray absorption spectroscopy, FTIR spectroscopy and in situ XRD. Both types are compared regarding kinetic properties for Li+ ion storage via cyclic voltammetry and impedance spectroscopy. A significant influence of particle morphology for 2D MOFs on kinetic aspects of electrochemical Li+ ion storage can be observed.

The width correlated with the surface charge induced in the dielectric films upon X-ray irradiation. The observed different binding energies observed for the N1s peak can only partly be associated with intrinsic work function differences between the samples, opening the possibility that the effect of physisorption at room temperature could be detected by a shift in the measured binding energy. However, the signals also show an increasing asymmetry with rising surface charge. This might be associated with the formation of vertical electrical gradients within the dielectric porous thin films, which complicates the assignment of binding energy positions to specific surface-related effects.

This leads to a different behavior regarding the molecular orientational freedom (‘structure of water') compared to the bulk liquid state. In addition to the pore size, the behavior is also strongly affected by the strength of the pore wall-to-water interactions, that is, the pore wall polarity. In this work, this is studied both experimentally and theoretically. The surface polarity of mesoporous silica (SiO2) is modified by functionalization with trimethylsilyl moieties, resulting in a change from a hydrophilic (pristine) to a hydrophobic pore wall. The mesopore surface is characterized by N2 and H2O sorption experiments. Those results are combined with IR spectroscopy to investigate pore wall-to-water interactions leading to different structures of water in the mesopore. Furthermore, the water's structure is studied theoretically to gain deeper insight into the interfacial interactions. For this purpose, the structure of water is analyzed by pairing densities, coordination, and angular distributions with a novel adaptation of surface-specific sum-frequency generation calculation for pore environments."}],"language":[{"iso":"eng"}],"article_number":"2200245","main_file_link":[{"open_access":"1","url":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202200245"}],"doi":"10.1002/admi.202200245","publication_identifier":{"issn":["2196-7350","2196-7350"]},"author":[{"id":"11848","full_name":"Weinberger, Christian","first_name":"Christian","last_name":"Weinberger"},{"first_name":"Frederik","last_name":"Zysk","full_name":"Zysk, Frederik","id":"14757"},{"full_name":"Hartmann, Marc","first_name":"Marc","last_name":"Hartmann"},{"full_name":"Kaliannan, Naveen","last_name":"Kaliannan","first_name":"Naveen"},{"full_name":"Keil, Waldemar","first_name":"Waldemar","last_name":"Keil"},{"first_name":"Thomas","last_name":"Kühne","full_name":"Kühne, Thomas","id":"49079"},{"id":"23547","last_name":"Tiemann","first_name":"Michael","orcid":"0000-0003-1711-2722","full_name":"Tiemann, Michael"}],"year":"2022","title":"The Structure of Water in Silica Mesopores – Influence of the Pore Wall Polarity","article_type":"original","intvolume":" 9","publication_status":"published","date_updated":"2023-03-03T11:33:24Z","oa":"1","citation":{"ieee":"C.

Although these materials have been widely studied for a variety of applications, the mechanisms underlying the pyrolysis are yet poorly understood. This study provides a comprehensive temperature-resolved characterization of the chemical composition, morphology and crystallinity of sucrose-derived hydrochar during pyrolysis. Thermogravimetric analysis, differential scanning calorimetry, and elemental analysis have shown that the dry hydrochar loses about 41% of its dry mass due to the exothermic disintegration of oxygen-containing groups until the carbonization is completed at about 850 °C with a total carbon yield of 93%. The carbonization and aromatization of the initially furanic and keto-aliphatic structure were analyzed by 13C solid-state nuclear magnetic resonance spectroscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The transition from an amorphous to a nanocrystalline graphitic structure was analyzed using X-ray diffraction and Raman spectroscopy. The pore formation mechanism was examined by helium ion microscopy, transmission electron microscopy, and nitrogen adsorption measurements. The results indicate the formation of oxygen-rich nanoclusters up to 700 °C, which decompose up to 750 °C leaving behind equally sized pores, resulting in a surface area of up to 480 m2/g."}],"date_created":"2022-01-18T06:25:06Z","type":"journal_article","keyword":["Analytical Chemistry","Fuel Technology"],"department":[{"_id":"35"},{"_id":"2"},{"_id":"307"},{"_id":"315"}],"year":"2022","title":"Pyrolysis of sucrose-derived hydrochar","author":[{"first_name":"Martin","last_name":"Wortmann","full_name":"Wortmann, Martin"},{"last_name":"Keil","first_name":"Waldemar","full_name":"Keil, Waldemar"},{"last_name":"Brockhagen","first_name":"Bennet","full_name":"Brockhagen, Bennet"},{"full_name":"Biedinger, Jan","first_name":"Jan","last_name":"Biedinger"},{"full_name":"Westphal, Michael","first_name":"Michael","last_name":"Westphal"},{"full_name":"Weinberger, Christian","last_name":"Weinberger","first_name":"Christian","id":"11848"},{"full_name":"Diestelhorst, Elise","last_name":"Diestelhorst","first_name":"Elise"},{"full_name":"Hachmann, Wiebke","last_name":"Hachmann","first_name":"Wiebke"},{"last_name":"Zhao","first_name":"Yanjing","full_name":"Zhao, Yanjing"},{"orcid":"0000-0003-1711-2722","first_name":"Michael","last_name":"Tiemann","full_name":"Tiemann, Michael","id":"23547"},{"full_name":"Reiss, Günter","first_name":"Günter","last_name":"Reiss"},{"full_name":"Hüsgen, Bruno","first_name":"Bruno","last_name":"Hüsgen"},{"first_name":"Claudia","last_name":"Schmidt","orcid":"0000-0003-3179-9997","full_name":"Schmidt, Claudia","id":"466"},{"full_name":"Sattler, Klaus","first_name":"Klaus","last_name":"Sattler"},{"full_name":"Frese, Natalie","first_name":"Natalie","last_name":"Frese"}],"publication_identifier":{"issn":["0165-2370"]},"date_updated":"2023-03-08T08:15:24Z","publication_status":"published","intvolume":" 161","article_type":"original","article_number":"105404","language":[{"iso":"eng"}],"doi":"10.1016/j.jaap.2021.105404"},{"page":"13-21","publisher":"Optica","_id":"28254","user_id":"23547","volume":12,"status":"public","oa":"1","citation":{"apa":"Geromel, R., Weinberger, C., Brormann, K., Tiemann, M., & Zentgraf, T.

The reflector stacks are fabricated in a layer-by-layer procedure by wet-chemical synthesis. They consist of low-ε porous SiO2 layers and high-ε TiO2 layers. Varying the thickness of the SiO2 layers allows tuning the optical bandgap in a wide range between ≈420 and 800 nm. A ZnO layer is deposited on top of the reflector stacks by sol–gel synthesis. The spontaneous photoluminescence (PL) emission of the ZnO film is modulated by the photonic structure. When the optical bandgap of the reflector is in resonance with the deep-level emission of ZnO (DLE, ≈500–530 nm), then this defect-related emission mode is suppressed. Strong NBE emission is observed even when the ZnO layer does not show any NBE emission (due to low crystallinity) in the absence of the photonic structure. With this cost-efficient synthesis method, emitters for, e.g., luminescent gas sensors can be fabricated.","lang":"eng"}],"publisher":"Wiley","_id":"29790","volume":9,"user_id":"23547","status":"public","oa":"1","citation":{"short":"L.
