Auttaphon Chachvalvutikul et al.

Summary: The fabrication of heterojunction photocatalysts with appropriate band potentials is an effective method to enhance photocatalytic properties by inhibiting electron-hole pair recombination. In this study, BiOBr, Bi4O5Br2, and Binary BiOBr/Bi4O5Br2 composites were synthesized using microwave irradiation, followed by the fabrication of FeVO4/Bi4O5Br2/BiOBr ternary composites with different weight percentages of FeVO4 for photocatalytic applications. The 1%wt-FeVO4/Bi4O5Br2/BiOBr photocatalyst showed superior visible-light-driven photocatalytic performance, with improved Cr(VI) photoreduction and simultaneous degradation of RhB in a combined system. Adjusting pH values and catalyst dosages maximized the removal of Cr(VI) and RhB. The study proposed a double Z-scheme charge transfer mechanism with an RhB-sensitized effect, leading to significant enhancement in charge segregation and migration, and higher redox properties of the ternary composite, resulting in excellent photocatalytic activity.
