摘要: BiVO4/Bi2WO6 composite photocatalysts were synthesized by coupling a homogeneous precipitation method with hydrothermal techniques. The as-prepared samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectrometry (FTIR), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), UV-Vis diffusion absorption spectroscopy (DRS) and photoluminescence (PL), respectively. The photocatalytic activities were evaluated by the degradation of methyl blue (MB) under visible …
