Figure 8. (A) LSV curves acquired in CO₂-saturated 0.5 M KHCO₃ solution on a rotating disc electrode at a rotating speed of 1,600 rpm. The inset highlights the LSV curves in the potential range from -0.1 to -0.7 V; (B) FE for CO production at various applied potentials; (C and D) COHP analysis of the Ni–C bond on NiN₄ and NiCuN₆; note that -COHP is used as the a-axis^[69].
