Recent advances and developments in solar-driven photothermal catalytic CO reduction into multicarbon (C) products.

Solar-driven catalytic conversion of carbon dioxide (CO) into value-added C chemicals and fuels has attracted significant attention over the past decades, propelled by urgent environmental and energy demands. However, the catalytic reduction of CO continues to face significant challenges due to inherently slow reduction kinetics. This review traces the historical development and current state of photothermal CO reduction, detailing the mechanisms by which CO is transformed into C products.
