Copper sulfide (CuS) catalysts continuously reconstruct their surface during electrochemical CO2 reduction, reports a study from the Institute of Science Tokyo, Japan. By uncovering the mechanism behind the dynamic surface changes that occur during potential-step electrolysis, the researchers revealed how sulfur and oxygen play distinct roles in catalyst activity and product selectivity, paving the way for improved CO2 conversion technologies.
