It is therefore an intriguing structure to study sorption phenomena. We analyze the water resistance and sorption behavior of these frameworks, with particular attention to the sorption mechanism in detail and the structure of the confined water molecules. For this purpose, we use manometric water vapor sorption analysis and FTIR spectroscopy. The respective metal center orchestrates both the adsorption behavior and the arrangement of the water molecules in the micropores of the framework. The extent to which water molecules form hydrogen bonds (with each other and with framework oxygen atoms) plays a crucial role in the stability of the framework towards water. Water adsorption is governed by the coordination of water molecules to the open metal sites (except for CPO-27-Cu) and subsequent H-bonding. A stepwise adsorption of water is observed, with significant differences depending on the choice of metal."}],"user_id":"23547","_id":"56265","language":[{"iso":"eng"}],"publication_identifier":{"issn":["1387-1811"]},"publication_status":"published","page":"113352","intvolume":"       381","citation":{"bibtex":"@article{Kloß_Weinberger_Tiemann_2025, title={Water in the Micropores of CPO-27 Metal-Organic Frameworks: A Comprehensive Study}, volume={381}, DOI={<a href=\"https://doi.org/10.1016/j.micromeso.2024.113352\">10.1016/j.micromeso.2024.113352</a>}, journal={Microporous and Mesoporous Materials}, publisher={Elsevier BV}, author={Kloß, Marvin and Weinberger, Christian and Tiemann, Michael}, year={2025}, pages={113352} }","short":"M.

Their structures lead to characteristic low-angle XRD signatures. We introduce a model based on geometrical considerations to simulate CMK-8 and CMK-9 structures with variable volume fraction of carbon (vs. pore volume, i.e., variable 'pore wall thickness'). In addition, we also simulate carbon materials with variable amounts of guest species (e.g., sulfur) residing in their pores. The corresponding XRD patterns are calculated. The carbon volume fraction turns out to have a significant impact on the relative diffraction peak intensities, especially in case of CMK-9 carbon that features a bimodal porosity. Likewise, the presence of guest species in the pores may also strongly affect the relative peak intensities. Our study suggests that careful evaluation of experimental low-angle XRD patterns of (real) CMK-8 or CMK-9 materials offers an opportunity to obtain detailed information about the nanostructural properties in addition to the mere identification of the pore systems geometry.","lang":"eng"}],"status":"public","publication":"Microporous and Mesoporous Materials","type":"journal_article","article_number":"110330","article_type":"original","language":[{"iso":"eng"}],"_id":"25894","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"user_id":"23547","year":"2021","citation":{"apa":"Schwind, B., Smått, J.-H., Tiemann, M., &#38; Weinberger, C.

Three different mixed-linker compounds with CAU-10 structure are compared regarding their water sorption and impedance characteristics. A setup was developed allowing the characterization of the MOF samples under exposure to different relative humidity values in air by impedance spectroscopy. Interpretation of the results by means of standard models shows that the MOFs are qualified for functional layers of capacitive humidity sensors.

Frequently, only bulk-phase densities are available which sometimes differ from those of porous samples, especially for amorphous systems, such as silica or carbon. The apparent density, i.e. the density of the sample excluding the gas-accessible pore volume, is typically determined by helium gas pycnometry utilizing specialized pycnometers. We demonstrate how to obtain the same data from standard N2 physisorption measurements as part of the regular measurement routine. We evaluate the method by reference measurements utilizing a non-porous reference sample (glass rod) to confirm the validity of the method.

The iron modification of the silica was performed according to a frequently used impregnation technique from aqueous iron nitrate solution. The materials were characterized by nitrogen physisorption, X-ray diffraction, TEM–EDX, Moessbauer spectroscopy, and temperature-programmed reduction (TPR) and tested in the catalytic decomposition of methanol. It is established that the location and dispersion of iron oxide nanoparticles are affected by the pore topology of the support. The most homogeneously dispersed iron oxide nanoparticles are observed using silica host matrix exhibiting a 3-D channel-like structure and pore diameters about 7 nm, and the thus-obtained composites exhibit high catalytic activity and selectivity in methanol decomposition to CO and hydrogen. For all the samples, characterized with a low mesopore volume and small pore diameters/pore entrances, the formation of larger iron oxide particles, mainly located on the outer surface, is observed. Inhomogeneously dispersed iron oxide particles with a large fraction of isolated, strongly interacting with the support, iron species, and possessing low catalytic activity and usually high selectivity to methane, are found for the silicas with relatively larger pores/pore entrances."}],"author":[{"full_name":"Tsoncheva, Tanya","last_name":"Tsoncheva","first_name":"Tanya"},{"first_name":"Jessica","last_name":"Rosenholm","full_name":"Rosenholm, Jessica"},{"full_name":"Linden, Mika","last_name":"Linden","first_name":"Mika"},{"first_name":"Freddy","full_name":"Kleitz, Freddy","last_name":"Kleitz"},{"id":"23547","full_name":"Tiemann, Michael","orcid":"0000-0003-1711-2722","last_name":"Tiemann","first_name":"Michael"},{"first_name":"Ljubomira","last_name":"Ivanova","full_name":"Ivanova, Ljubomira"},{"last_name":"Dimitrov","full_name":"Dimitrov, Momtchil","first_name":"Momtchil"},{"last_name":"Paneva","full_name":"Paneva, Daniela","first_name":"Daniela"},{"full_name":"Mitov, Ivan","last_name":"Mitov","first_name":"Ivan"},{"full_name":"Minchev, Christo","last_name":"Minchev","first_name":"Christo"}],"date_created":"2021-10-09T06:53:42Z","date_updated":"2023-03-09T08:44:27Z","doi":"10.1016/j.micromeso.2007.10.005","title":"Critical evaluation of the state of iron oxide nanoparticles on different mesoporous silicas prepared by an impregnation method","publication_identifier":{"issn":["1387-1811"]},"quality_controlled":"1","publication_status":"published","page":"327-337","citation":{"short":"T.

XRD, TEM-EDX, N2 physisorption, FTIR, and Moessbauer spectroscopy are used for their characterization. The reductive properties and catalytic behaviour in methanol decomposition of the materials are also studied. Depending on the chemical nature of the support, the predominant formation of: isolated iron species, strongly interacting with the support (for SBA-15), mixture of hematite and binary MgFe2O4 nanoparticles (for MgO) or almost homogeneously dispersed hematite particles (for CeO2) are observed. The state of iron species strongly affects their catalytic properties. The favorable effect of the support mesoporosity on the catalytic activity is most pronounced for the iron modified CeO2.","lang":"eng"}],"status":"public","publication":"Microporous and Mesoporous Materials","type":"journal_article","article_type":"original","extern":"1","language":[{"iso":"eng"}],"_id":"25982","department":[{"_id":"35"},{"_id":"2"},{"_id":"307"}],"user_id":"23547"},{"quality_controlled":"1","publication_identifier":{"issn":["1387-1811"]},"publication_status":"published","year":"2007","page":"335-341","citation":{"ieee":"J.

Nitrogen physisorption, powder X-ray diffraction, transmission electron microscopy (TEM), selected-area electron diffraction (SAED), energy-dispersive X-ray (EDX), X-ray absorption near-edge structure (XANES), and thermal (TG/MS) analysis were used for their characterisation. Methanol decomposition to hydrogen, CO, and methane was used as a catalytic test reaction. The obtained products exhibit uniform pores with a diameter of ca. 5 nm in a two-dimensional hexagonal periodic arrangement, as well as interparticle porosity, broadly distributed around ca. 35 nm; the specific surface area is 148 m2 g−1. The pore walls are polycrystalline. The polycrystalline nature and high surface-to-volume ratio of the products is reflected in an increased signal intensity in X-ray absorption spectroscopy. The synthesis of CeO2 from Ce(NO3)3 within the pores of the carbon matrix and the subsequent thermal combustion of the carbon is monitored by thermal analysis. Catalytic tests reveal that the activity of the mesoporous products in methanol decomposition are substantially higher than for a non-porous sample."}],"status":"public","_id":"25987","department":[{"_id":"35"},{"_id":"163"},{"_id":"307"}],"user_id":"23547","article_type":"original","extern":"1","language":[{"iso":"eng"}]}]
