相邻活性位点间的协同作用可以促进催化活性，同时保持源自原子分散性质的高原子利用率，双金属位点催化剂正成为CO₂还原反应研究中的新领域。锚定在氮化碳上的原子级分散的Ni/Co双金属活性位点，可作为一种高效的CO₂电还原催化剂。该催化剂在-0.6~-1.1 V的宽电势范围内表现出优异的选择性（CO法拉第效率超过90%），并且在连续电解40 h后仍保持94%的初始选择性，显示出卓越的稳定性。

The synergy between adjacent active sites can promote catalytic activity while maintaining high atomic utilization sourced from atomic dispersion properties.Bimetallic site catalyst is becoming a new item in studying CO₂ electroreduction reaction.The isolated Ni-Co bimetal active sites anchored on carbon nitride can be used as an efficient catalyst for electroreduction of CO₂.This catalyst exhibits excellent selectivity in a wide potential range from -0.6 to -1.1 V vs.RHE (CO Faraday efficiency exceeds 90%),and maintains an initial selectivity of 94% after 40 hours of continuous electrolysis,showing significant stability.This work provides a new perspective for advancing universal synthesis strategies to construct heteronuclear diatomic catalysts.
