Modulating the local coordination structure of metal single-atom catalysts(SACs)is extensively employed to tune the catalytic activity,but rarely involved in regulating the reaction pathway which fundamentally determines the product ***,we report that the product selectivity of electrochemical CO_(2)reduction(CO_(2)RR)on the single-atom indium-NxC4-x(1≤x≤4)catalysts could be tuned from formate to CO by varying the carbon and nitrogen occupations in the first coordination ***,the optimal In SAC showed great promise for CO production with the maximum Faradic efficiency of 97%,greatly different from the reported In-based catalysts where the formate is the dominant *** experimental verifications and theoretical simulations reveal that the selectivity switch from formate to CO on In SACs originates from active sites shift from indium center to the indium-adjacent carbon atom,where the indium site favors formate formation and the indium-adjacent carbon site prefers the CO *** present work suggests the active sites in metal SACs may shift from the widely accepted metal center to surrounding carbon atoms,thereby offering a new implication to revisit the active sites for metal SACs.
