Abstract In order to explore the stability and availability of BiVO4 photocatalyst in real life. BiVO4 was prepared by using NH4VO3 and Bi(NO3)3·5H2O as raw material. The structural properties and morphological characteristics of BiVO4 samples were explored by characterization means. With phenol simulation wastewater as the target pollutant, the target pollutant was degraded by photocatalytic experiments to verify the photocatalytic effect of BiVO4, and the preparation method and process of 3 D floral BiVO4 with the best catalytic performance were continuously explored. The control experiment was designed to verify the main effect of light on the experiment. Through the quenching experiment, the main active substance of BiVO4 in the photocatalytic reaction was explored, and finally the cycle experiment was designed to explore the actual availability of life. The results show that degradation rate of 80.09% 3 D floral microsphere BiVO4 photocatalyst is stable and has real-life availability.

Key words： three-dimensional flower BiVO4 hydrothermal method photocatalysis phenol degradation mechanism
