The design of catalytic sites with tunable properties is considered a promising approach to advance the reduction of CO2 into valuable fuels and chemicals, as well as to achieve carbon neutrality. However, significant challenges remain in precisely constructing catalytic sites to adjust target reduction products. In this study, catalysts were derived from metal‐organic frameworks (MOFs) with different coordination environments during the electrochemical CO2 reduction reaction (eCO2RR), referred to as Cu‐N2O2 and Cu‐N2O3, respectively. Higher selectivity towards the production of C2 products was exhibited by the Cu‐N2O2‐derived catalysts, characterized by asymmetric catalytic centers of Cu0 and Cu+, compared to the Cu‐N2O3‐derived catalysts, which contained only symmetric catalytic centers of Cu0 sites. This enhanced selectivity is attributed to the synergistic interaction between the Cu0 and Cu+ sites, facilitating the multi‐electron transfer process and improving the activation of CO2. This study explores how the coordination environment affects the catalytic performance of catalysts derived from MOFs, providing valuable insights for the development of more effective catalysts aimed at CO2 reduction.
