AbstractThe high concentrations of CO2 in industrial flue gases make these point sources attractive candidates for renewably powered electrocatalytic conversion of CO2 to products. However, trace SO2 in common flue gases rapidly and irreversibly poisons catalysts. Here we report that limiting hydrogen adsorption in the vicinity of electrochemically active sites deactivates SO2 to enable efficient CO2 conversion.

AbstractThe carbon dioxide and carbon monoxide electroreduction reactions, when powered using low-carbon electricity, offer pathways to the decarbonization of chemical manufacture1,2. Copper (Cu) is relied on today for carbon–carbon coupling, in which it produces mixtures of more than ten C2+ chemicals3,4,5,6: a long-standing challenge lies in achieving selectivity to a single principal C2+ product7,8,9.
