Abstract

We report a fascinating solid-phase synthesis of ultra-small CuMo solid solution alloy nanoclusters (2.1 nm) anchored on electrospun carbon nanofibers (CuMo/CNFs). By tuning the weight ratio of Cu and Mo, the optimized Cu₂Mo₁/CNFs achieves excellent CO₂RR performance with a high faradaic efficiency (FE) of 84.5% for C₂₊ products and an FE_ethanol of 75.7%. In situ characterization demonstrates that the Cu₂Mo₁ alloy can strengthen the adsorption of the crucial intermediate and promote C-C coupling, leading to high selectivity and efficiency for C₂₊ products.
