Fabrication and photocatalytic performance of Bi24O31Br10 nanosphere by a polyacrylamide gel method

The authors have fabricated novel flower-like Bi24O31Br10 micro/nanospheres by a polyacrylamide gel method. The crystal structure, microstructure, bandgap, morphology, and optical property of the as-prepared Bi24O31Br10 micro/nanospheres were investigated by multiple techniques. The Bi24O31Br10 photocatalyst exhibits excellent photocatalytic performance for the degradation of methyl orange under visible light irradiation. Furthermore, the cycle experimental results show that the Bi24O31Br10 micro/nanospheres possess superior reusability. The possible photocatalytic work principle was proposed and discussed.
