Selective CO₂ electrolysis to CO using isolated antimony alloyed copper.

ABSTRACT: Renewable electricity-powered CO evolution from CO₂ emissions is a promising first step in the sustainable production of commodity chemicals, but performing electrochemical CO₂ reduction economically at scale is challenging since only noble metals, for example, gold and silver, have shown high performance for CO₂-to-CO. Cu is a potential catalyst to achieve CO₂ reduction to CO at the industrial scale, but the C-C coupling process on Cu significantly depletes CO* intermediates, thus limiting the CO evolution rate and producing many hydrocarbon and oxygenate mixtures. Herein, we tune the CO selectivity of Cu by alloying a second metal Sb into Cu, and report an antimony-copper single-atom alloy catalyst (Sb₁Cu) of isolated Sb-Cu interface
