摘要
Photocatalytic CO2 reduction to value‐added fuels displays an attractive scenario to enhance energy supply and reduce global warming. We report herein the confinement synthesis of polymeric carbon nitride (PCN) incorporating with Cu single atoms (CuSAs) inside the crystalline UiO‐66‐NH2, which combines the merits of heterojunction photocatalysis and single‐atom catalysis (SAC) to achieve high‐performance CO2‐to‐CH3OH conversion. A series of spectral studies displays the formation of CuSAs@PCN inside the crystalline UiO‐66‐NH2. Remarkably, the ternary composite shows an excellent photocatalytic turnover frequency of 4.15 mmol·h‐1·g‐1 for CO2‐to‐CH3OH conversion. Theoretical and experimental studies demonstrate the doping of CuSAs, as well as the formation of type‐II heterojunction, are causal factors to achieve CH3OH generation. The study provides new insights designing high‐performance photocatalyst for CO2 conversion to fuels at atomic scale.
