Turning copper into an efficient and stable CO evolution catalyst beyond noble metals.

ABSTRACT: Using renewable electricity to convert CO₂ into CO offers a sustainable route to produce a versatile intermediate to synthesize various chemicals and fuels. For economic CO₂-to-CO conversion at scale, however, there exists a trade-off between selectivity and activity, necessitating the delicate design of efficient catalysts to hit the sweet spot. We demonstrate here that copper co-alloyed with isolated antimony and palladium atoms can efficiently activate and convert CO₂ molecules into CO. This trimetallic single-atom alloy catalyst (Cu₉₂Sb₅Pd₃) achieves an outstanding CO selectivity of 100% (±1.5%) at -402 mA cm^-2 and a high activity up to -1 A cm^-2 in a neutral electrolyte, surpassing numerous state-o
