Fabrication of the heterojunction photocatalyst with appropriate band potentials as a promising method inhibiting electron-hole pair recombination leading to enhanced photocatalytic properties. Herein, BiOBr, Bi 4 O 5 Br 2 , and binary BiOBr/Bi composite were selectively synthesized by employing one-step microwave irradiation method. Then, double Z-scheme FeVO /Bi /BiOBr ternary composites diff...
