Abstract

Abstract

Three-dimensional Bi₂MoO₆/ZnO microflowers composed of nano-sheets were synthesized by two-step hydrothermal method. By changing the content of Bi₂MoO₆ in the composite, a series of Bi₂MoO₆/ZnO microflowers with different molar ratios were prepared. The results showed that the photocatalytic degradation rate of Bi₂MoO₆/ZnO−10% composite to RhB solution reached 79.61% after 20 min of visible light irradiation. Compared with pure ZnO and Bi₂MoO₆, the composite had better photocatalytic performance. Through the analysis of ultraviolet visible (UV−Vis) spectrum and room temperature fluorescence spectra (PL), it is further speculated that the improvement of the photocatalytic performance of Bi₂MoO₆/ZnO microflora is due to the improvement of the optical absorption range of the composite and the formation of heterojunction, which inhibits the recombination of photogenerated carriers.
