| 英文摘要 | Electrocatalytic co2 reduction to co emerges as a potential route of utilizing emitted co2. metal-n-c hybrid structures have shown unique activities, however, the active centers and reaction mechanisms remain unclear because of the ambiguity in true atomic structures for the prepared catalysts. herein, combining density-functional theory calculations and experimental studies, the reaction mechanisms for well-defined metal-n-4 sites were explored using metal phthalocyanines as model catalysts. the theoretical calculations reveal that cobalt phthalocyanine exhibits the optimum activity for co2 reduction to co because of the moderate *co binding energy at the co site, which accommodates the *cooh formation and the *co desorption. it is further confirmed by experimental studies, where cobalt phthalocyanine delivers the best performance, with a maximal co faradaic efficiency reaching 99%, and maintains stable performance for over 60 hours. |
