Fully exposed nickel clusters with electron-rich centers for high-performance electrocatalytic CO2 reduction to CO
文献摘要：
Single-atom catalysts(SACs)have attracted increasing concerns in electrocatalysis because of their max-imal metal atom utilization,distinctive electronic properties,and catalytic performance.However,the isolated single sites are disadvantageous for reactions that require simultaneously activating different reactants/intermediates.Fully exposed metal cluster catalyst(FECC),inheriting the merits of SACs and metallic nanoparticles,can synergistically adsorb and activate reactants/intermediates on their multi-atomic sites,demonstrating great promise in electrocatalytic reactions.Here a facile method to regulate the atomic dispersion of Ni species from cluster to single-atom scale for efficient CO2 reduction was developed.The obtained Ni FECC exhibits high Faradaic efficiency of CO up to 99％,high CO partial current density of 347.2 mA cm-2,and robust durability under 20 h electrolysis.Theoretical calculations illumi-nate that the ensemble of multiple Ni atoms regulated by sulfur atoms accelerates the reaction kinetics and thus improves CO production.
