[{"status":"public","abstract":[{"lang":"eng","text":"Self-templating is a facile strategy for synthesizing porous carbons by direct pyrolysis of organic metal salts. However, the method typically suffers from low yields (<4%) and limited specific surface areas (SSA<2000 m2 g−1) originating from low activity of metal cations (e.g., K+ or Na+) in promoting construction and activation of carbon frameworks. 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. This study helps to understand and rationally tailor the materials design by a still rare organic solid-state chemistry."}],"type":"journal_article","publication":"Angewandte Chemie International Edition","language":[{"iso":"eng"}],"article_type":"original","keyword":["CO2 Adsorption","Cesium Acetate","Cesium Effect","Porous Carbons","Supercapacitor"],"user_id":"11848","_id":"45571","citation":{"mla":"Li, Jiaxin, et al. “When High‐Temperature Cesium Chemistry Meets Self‐Templating: Metal Acetates as Building Blocks of Unusual Highly Porous Carbons.” <i>Angewandte Chemie International Edition</i>, Wiley, 2023, doi:<a href=\"https://doi.org/10.1002/anie.202217808\">10.1002/anie.202217808</a>.","bibtex":"@article{Li_Kossmann_Zeng_Zhang_Wang_Weinberger_Antonietti_Odziomek_López‐Salas_2023, title={When High‐Temperature Cesium Chemistry Meets Self‐Templating: Metal Acetates as Building Blocks of Unusual Highly Porous Carbons}, DOI={<a href=\"https://doi.org/10.1002/anie.202217808\">10.1002/anie.202217808</a>}, journal={Angewandte Chemie International Edition}, publisher={Wiley}, author={Li, Jiaxin and Kossmann, Janina and Zeng, Ke and Zhang, Kun and Wang, Bingjie and Weinberger, Christian and Antonietti, Markus and Odziomek, Mateusz and López‐Salas, Nieves}, year={2023} }","short":"J.

Therefore, understanding its structure is crucial for the progress of sustainable technologies. We extract new physico‐chemical information on the capacitance and structure of the electrical double‐layer of platinum and gold nanoparticles at the molecular level, employing single nanoparticle electrochemistry. The charge storage ability of the solid/liquid interface is larger by one order‐of‐magnitude than predicted by the traditional mean‐field models of the double‐layer such as the Gouy–Chapman–Stern model. Performing molecular dynamics simulations, we investigate the possible relationship between the measured high capacitance and adsorption strength of the water adlayer formed at the metal surface. These insights may launch the active tuning of solid–solvent and solvent–solvent interactions as an innovative design strategy to transform energy technologies towards superior performance and sustainability.","lang":"eng"}]},{"keyword":["supercapacitor","carbon","pyrolysis","lignin"],"language":[{"iso":"eng"}],"abstract":[{"text":"We report on the facile synthesis of porous carbons based on a biopolymer lignin employing a two-step process which includes the activation by KOH in various amounts under an inert gas atmosphere. The resulting carbons are characterized with regard to their structural properties and their electrochemical performance as an active material in double-layer capacitors using for the first time an ionic liquid (EMIBF4) as the electrolyte for this type of carbon material to enhance storage ability. A capacitance of more than 200 F g–1 at 10 A g–1 is achieved for a carbon with a specific surface area of more than 1800 m2 g–1. One of the most crucial factors determining the electrochemical response of the active materials was found to be the strong surface functionalization by oxygen-containing groups. Furthermore, the sulfur content of the carbon precursor lignin does not result in a significant amount of sulfur-containing surface functionalities which might interact with the electrolyte.","lang":"eng"}],"publication":"ACS Sustainable Chemistry & Engineering","title":"Softwood Lignin as a Sustainable Feedstock for Porous Carbons as Active Material for Supercapacitors Using an Ionic Liquid Electrolyte","publisher":"American Chemical Society (ACS)","date_created":"2025-12-03T15:33:13Z","year":"2017","quality_controlled":"1","issue":"5","article_type":"original","extern":"1","_id":"62804","department":[{"_id":"985"}],"user_id":"116779","status":"public","type":"journal_article","doi":"10.1021/acssuschemeng.7b00058","date_updated":"2025-12-03T16:36:06Z","volume":5,"author":[{"last_name":"Klose","full_name":"Klose, Markus","first_name":"Markus"},{"last_name":"Reinhold","full_name":"Reinhold, Romy","first_name":"Romy"},{"first_name":"Florian","last_name":"Logsch","full_name":"Logsch, Florian"},{"first_name":"Florian","last_name":"Wolke","full_name":"Wolke, Florian"},{"first_name":"Julia","id":"116779","full_name":"Linnemann, Julia","last_name":"Linnemann","orcid":"0000-0001-6883-5424"},{"first_name":"Ulrich","full_name":"Stoeck, Ulrich","last_name":"Stoeck"},{"last_name":"Oswald","full_name":"Oswald, Steffen","first_name":"Steffen"},{"first_name":"Martin","full_name":"Uhlemann, Martin","last_name":"Uhlemann"},{"first_name":"Juan","last_name":"Balach","full_name":"Balach, Juan"},{"last_name":"Markowski","full_name":"Markowski, Jens","first_name":"Jens"},{"first_name":"Peter","last_name":"Ay","full_name":"Ay, Peter"},{"first_name":"Lars","last_name":"Giebeler","full_name":"Giebeler, Lars"}],"intvolume":"         5","page":"4094-4102","citation":{"apa":"Klose, M., Reinhold, R., Logsch, F., Wolke, F., Linnemann, J., Stoeck, U., Oswald, S., Uhlemann, M., Balach, J., Markowski, J., Ay, P., &#38; Giebeler, L.
