Abstract The photothermal conversion of CO 2 provides a straightforward and effective method for the highly efficient production solar fuels with high solar‐light utilization efficiency. This is due to several crucial features Group VIII nanocatalysts, including energy over whole range spectrum, excellent performance, unique activation abilities. Photothermal reaction rates (mol h −1 g ) that are orders magnitude larger than those obtained photocatalytic methods (μmol were thus achieved. It proposed overall water‐based process can be achieved by combining light‐driven H from water . More generally, this work suggests traditional catalysts characterized intense photoabsorption will find new applications in photo‐induced green‐chemistry processes.
