Splicing the active phases of copper/cobalt-based catalysts achieves high-rate tandem electroreduction of nitrate to ammonia

Autor: Wenhui He, Jian Zhang, Stefan Dieckhöfer, Swapnil Varhade, Ann Cathrin Brix, Anna Lielpetere, Sabine Seisel, João R. C. Junqueira, Wolfgang Schuhmann

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-13 (2022)

Electrocatalytic recycling of waste nitrate to NH3 under ambient conditions maybe an appealing alternative to the Haber−Bosch process. Here the authors report a tandem catalyst system involving cooperative adsorption of reaction intermediate on dif

B‐Cu‐Zn Gas Diffusion Electrodes for CO 2 Electroreduction to C 2+ Products at High Current Densities

Autor: Corina Andronescu, Nivedita Sikdar, Denis Öhl, João R. C. Junqueira, Sabine Seisel, Yanfang Song, Wolfgang Schuhmann, Thomas Quast, Stefan Dieckhöfer, Justus Masa

Publikováno v: Angewandte Chemie International Edition

Electroreduction of CO2 to multi-carbon products has attracted considerable attention as it provides an avenue to high-density renewable energy storage. However, the selectivity and stability under high current densities are rarely reported. Herein,
