A series of Zn(Fe x Ga 1‐ x ) 2 O 4 solid solutions were synthesized by using a sol‐gel method, and their photocatalytic CO 2 reduction performance was investigated under simulated solar‐light irradiation. The content ratio of Fe 3+ and Ga 3+ not only greatly determined the light‐harvesting capability of Zn(Fe x Ga 1‐ x ) 2 O 4 in the ultraviolet and visible‐light regions, but also regulated the positions of the VB‐top and CB‐bottom potentials, ultimately greatly affecting the photocatalytic capabilities. ZnFe 0.1 Ga 1.9 O 4 , the optimum Fe 3+ content isomorphism presented the maximum CH 4 formation rate of 6.1 µmol/h at 30 °C among the Zn(Fe x Ga 1‐ x ) 2 O 4 solid solutions.
