Cu‒S Covalent Bonds Enable the Anchoring of Single‐atom Cu on Layered MoS2 for Highly Selective and Active Photothermal Catalytic Conversion of CO2−H2O to Ethanol

open access: yesAdvanced Science, EarlyView.
Cu5%‐MoS2 with dual Cu and Mo active sites enables efficient photothermal synergistic catalysis of the CO2–H2O system for ethanol production. The catalyst achieves a high ethanol yield of 3.1 mmol·g−1·h−1 with 88.35% selectivity, showcasing exceptional performance and selectivity under mild conditions. Abstract The catalytic conversion of CO2 into high‐
