Synthesis of hierarchical bismuth-rich Bi4O5BrxI2-x solid solutions for enhanced photocatalytic activities of CO2 conversion and Cr(VI) reduction under visible light
Bismuth-rich Bi4O5BrxI2-x solid solutions were prepared for the first time. Bi4O5BrxI2-x were used for photocatalytic CO2 conversion and Cr(VI) removal. At x = 1, Bi4O5BrI showed the highest photocatalytic activities.
