摘要：

The novel visible light-induced carbon nitride(g-C3N4) and Bi VO4 composite photocatalysts were obtained through a simple mixing-calcination method. The physical and photophysical properties of the Bi VO4-g-C3N4 composites were investigated by X-ray diffraction(XRD), Fourier transform infrared(FTIR) spectroscopy, UV-vis diffuse reflection spectroscopy, high-resolution transmission electron microscopy(HRTEM), photoluminescent(PL) spectroscopy, and BET surface area measurements. Photocatalytic oxidation ability of the prepared samples was examined by studying the degradation of rhodamine B(Rh B) as a target pollutant under visible-light irradiation. The composite photocatalysts exhibited an enhanced photocatalytic performance in degrading Rh B. The optimal g-C3N4 content of the composite photocatalysts was determined for the photodegradation activity. The improved photocatalytic activity of the as-prepared composite photocatalyst may be attributed to the enhancement of photo-generated electron-hole separation at the interface.
