Cobalt phthalocyanine (CoPc) is an appealing electrocatalyst for CO2 reduction. However, its catalytic performance is limited by instability and low conductivity. Herein, theoretical calculations reveal that nitrogen-rich carbon nitride, as a promising Supporting material, can help to tune the electronic structure of CoPc and then enhance its stability and conductivity by inducing electron delocalization of Co-N4 sites for the formation of Co-N5, achieving a superior electrochemical reduction of CO2. Inspired by this prediction, we prepared nit...
