In this study, copper/zinc oxide/graphite nitrogen carbide (Cu/ZnO/g‐C 3 N 4 ) is prepared using a hydrothermal method and applied as a photocatalyst for CO 2 photoreduction. The morphology and structural properties of the obtained Cu/ZnO/g‐C 3 N 4 are systematically characterized through X‐ray powder diffraction, ultraviolet–visible absorption spectroscopy, transmission electronic microscopy, and photoluminescence spectroscopy. A 3 wt% Cu/ZnO/g‐C 3 N 4 photocatalyst exhibits high CH 4 (40.7 μmol g −1 hr −1 ), CO (65.1 μmol g −1 hr −1 ), and CH 3 OH (92.5 μmol g −1 hr −1 ) production rates, which are 38.3, 77.1, and 58.1 fold higher than the pure g‐C 3 N 4 . The production rate is higher than those for bulk g‐C 3 N 4 and ZnO/g‐C 3 N 4 . Finally, the reaction mechanism of Cu/ZnO/C 3 N 4 is proposed in this study.
