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.","lang":"eng"}],"publication":"Angewandte Chemie International Edition","article_type":"original","publication_status":"published","doi":"10.1002/anie.202217808","date_created":"2023-06-12T07:42:09Z","status":"public","_id":"45571","publication_identifier":{"issn":["0044-8249","1521-3757"]},"user_id":"11848","year":"2023","author":[{"first_name":"Jiaxin","full_name":"Li, Jiaxin","last_name":"Li"},{"full_name":"Kossmann, Janina","last_name":"Kossmann","first_name":"Janina"},{"first_name":"Ke","full_name":"Zeng, Ke","last_name":"Zeng"},{"last_name":"Zhang","full_name":"Zhang, Kun","first_name":"Kun"},{"last_name":"Wang","full_name":"Wang, Bingjie","first_name":"Bingjie"},{"last_name":"Weinberger","full_name":"Weinberger, Christian","first_name":"Christian","id":"11848"},{"first_name":"Markus","full_name":"Antonietti, Markus","last_name":"Antonietti"},{"first_name":"Mateusz","full_name":"Odziomek, Mateusz","last_name":"Odziomek"},{"first_name":"Nieves","last_name":"López‐Salas","full_name":"López‐Salas, Nieves"}],"keyword":["CO2 Adsorption","Cesium Acetate","Cesium Effect","Porous Carbons","Supercapacitor"],"type":"journal_article","publisher":"Wiley","citation":{"ama":"Li J, Kossmann J, Zeng K, et al.
