The AgBr/BiVO4 heterostructure were synthesized. The heterostructure materials were characterized by XRD, DRS, SEM-EDS, TEM, XPS and TG-DSC. In order to investigate the photocatalytic activity of AgBr/BiVO4 heterostructures, the methylene blue (MB) dye was used as a model compound. The result suggested that under visible light irradiation, the degradation efficiency of AgBr/BiVO4 reached 83.1% within 2.5 h, which was higher than that of the pure BiVO4. The presence of AgBr significantly increased the photocatalytic activity of the composites. The photocatalytic mechanism was also discussed.
合成了AgBr/BiVO₄异质结构。通过XRD、DRS、SEM-EDS、TEM、XPS和TG-DSC对异质结构材料进行了表征。为了研究AgBr/BiVO₄异质结构的光催化活性，以亚甲基蓝（MB）染料作为模型化合物。结果表明，在可见光照射下，AgBr/BiVO₄在2.5小时内的降解效率达到83.1%，高于纯BiVO₄。AgBr的存在显著提高了复合材料的光催化活性。还讨论了光催化机理。
