Constructing a square-like copper cluster to boost C–C coupling for CO 2 electroreduction to ethylene

By DFT computations, we proposed Cu 5 @MoS 2 —an anchored Cu 5 cluster on defective MoS 2 —as a promising catalyst for CO 2 -to-ethylene conversion. With distinctive square-like sites, Cu 5 @MoS 2 demonstrates remarkable activity and selectivity, particularly in alkaline conditions.
