Oxygen-affinity engineering on single-site catalysts for selective CO2 electroreduction

Controlling the selectivity-determining step (SDS) in post-C–C coupling is crucial to produce C2 chemicals during electrocatalytic CO2 reduction. In a recent Nature Chemical Engineering article, Li et al. report a generalizable oxygen-affinity engineering strategy to manipulate the SDS on the surface of single-site noble-metal-doped Cu catalysts, facilitating selective CO2 electroreduction pathway for a single C2 product.
