Transition Metals Doped into g-CN via N,O Coordination as Efficient Electrocatalysts for the Carbon Dioxide Reduction Reaction.

The electrochemical carbon dioxide reduction reaction (CORR) is a potential and efficient method that can directly convert CO into high-value-added chemicals under mild conditions. Owing to the exceptionally high activation barriers of CO, catalysts play a pivotal role in CORR. In this study, the transition metal (TM = Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn) is doped into g-CN with a unique N,O-coordination environment, namely, TM-NO/g-CN.
