Boosting Electrochemical Carbon Dioxide Reduction on Atomically Dispersed Nickel Catalyst.

ABSTRACT: Single-atom catalysts (SACs) with metal-nitrogen (M-N) sites are one of the most promising electrocatalysts for electrochemical carbon dioxide reduction (ECO₂R). However, challenges in simultaneously enhancing the activity and selectivity greatly limit the efficiency of ECO₂R due to the improper interaction of reactants/intermediates on these catalytic sites. Herein, we report a carbon-based nickel (Ni) cluster catalyst containing both single-atom and cluster sites (NiNx-T, T = 500-800) through a ligand-mediated method and realize a highly active and selective electrocatalytic CO₂R process. The catalytic performance can be regulated by the dispersion of Ni-N species via controlling the pyrolysis condition. Benefitting from the synergistic effect of p
