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","doi":"10.1002/anie.202217808","title":"When High‐Temperature Cesium Chemistry Meets Self‐Templating: Metal Acetates as Building Blocks of Unusual Highly Porous Carbons","author":[{"first_name":"Jiaxin","last_name":"Li","full_name":"Li, Jiaxin"},{"first_name":"Janina","last_name":"Kossmann","full_name":"Kossmann, Janina"},{"first_name":"Ke","last_name":"Zeng","full_name":"Zeng, Ke"},{"first_name":"Kun","last_name":"Zhang","full_name":"Zhang, Kun"},{"full_name":"Wang, Bingjie","last_name":"Wang","first_name":"Bingjie"},{"first_name":"Christian","full_name":"Weinberger, Christian","id":"11848","last_name":"Weinberger"},{"last_name":"Antonietti","full_name":"Antonietti, Markus","first_name":"Markus"},{"first_name":"Mateusz","last_name":"Odziomek","full_name":"Odziomek, Mateusz"},{"last_name":"López‐Salas","full_name":"López‐Salas, Nieves","first_name":"Nieves"}],"date_created":"2023-06-12T07:42:09Z","date_updated":"2024-03-21T12:01:33Z","publisher":"Wiley","citation":{"apa":"Li, J., Kossmann, J., Zeng, K., Zhang, K., Wang, B., Weinberger, C., Antonietti, M., Odziomek, M., &#38; López‐Salas, N.
