AgBr/ZnO composite photocatalyst was prepared by a simple one-step hydrothermal method. The composites were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, ultraviolet-visible spectroscopy and photoluminescence spectroscopy. The effect of AgBr/ZnO system synthesis on the photocatalytic properties of the materials was analyzed. The photocatalytic activity of the composite catalyst was investigated with rhodamine B solution as a target pollutant. The results show that an optimum AgBr/ZnO-2 composite with a molar ratio of AgBr to ZnO of 1∶5 has a degradation rate of rhodamine B of 98.98% for 60 min under visible light irradiation. Compared to ZnO, the photocatalytic activity is improved and the degradation rate constant is increased by 11.08 times. Compared to commercial TiO2(P25), the degradation rate constant is increased by 10.14 times. That is mainly since AgBr/ZnO has a lower electron-hole recombination ratio than ZnO, and the optical absorption band edge of the composite catalyst is red-shifted, thereby enhancing the absorption of visible light.
