Efficient Low-Coordination Copper-Based Catalysts for Selective CO2 Reduction to Ethylene
According to previous literature, the C-C coupling step in the CO2RR reaction is widely considered to be the core for producing C2 products, especially ethylene. Therefore, adjusting the spatial configuration of Cu to modulate the adsorption of *CO, thereby facilitating CO-CO coupling, is regarded as an effective method to promote ethylene production.The strong adsorption of *CO and the enhanced selectivity for C2+ due to low-coordination sites are particularly significant. However, under catalytic conditions (such as pH, potential, and electrolyte), most
