Microwave-Assisted Hydrothermal Synthesis of Ag/BiVO₄ Architecture with Enhanced Photocatalytic Activities

Abstract:

BiVO4 microcrystals were prepared via a microwave-assisted hydrothermal process. Ag loaded BiVO4 photocatalyst was prepared by a photoreduction process. XRD, UV-Vis-DRS and FE-SEM techniques were employed to investigate its’ phase composition, absorption property and morphology. The photocatalytic activity of the as-prepared samples was evaluated by the degradation ratio of Rhodamine B. The result indicated that the as-synthesized BiVO4 are spherical microcrystals built up by square nanoplates. After Ag nanoparticles deposite, the photocatalytic activity of BiVO4 was greatly enhanced. Furthermore, the photoctalytic activity enhancement mechanism was also discussed.
