摘要：

Visible-light-driven Ag3VO4/Bi2WO6 photocatalysts with different weight contents of Ag(3)VO(4 )used for degradation of rhodamine B (RhB) were successfully synthesized by a deposition-precipitation method. The as-prepared pure Bi2WO6 sample and heterostructure Ag3VO4/Bi2WO6 nanocomposites were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HRTEM) and selected area electron diffraction (SAED). In this research, the Ag(3)VO(4 )nanoparticles were supported on thick Bi2WO6 nanoplates. The heterostructure 10 wt% Ag3VO4/Bi2WO6 nanocomposites showed the highest photocatalytic performance for RhB degradation of 95% under visible light irradiation within 80 min due to the separation of photo-excited charge carriers and inhibition of photo-induced electron-hole pairs.
