Highly efficient electrochemical CO2-to-CO conversion is a promising approach for achieving carbon neutrality. While nonmetallic electrocatalysts have shown potential utilization in H-type cells, flow cells at an industrial scale remains challenging. In this study, we present cost-effective synthesis strategy preparing ultrathin 2D nanosheet catalysts through simple amine functionalization. The optimized catalyst, NCNs-2.5, demonstrates exceptional CO selectivity with maximum Faradaic efficiency of 98% and achieves high current density 55 mA cm-2 cell. Furthermore, the catalyst exhibits excellent long-term stability, operating continuously 50 h while maintaining above 90%. superior catalytic activity NCNs-2.5 attributed to presence amine-N active sites within lattice structure.
