New insight into the photocatalytic degradation of organic pollutant over BiVO4/SiO2/GO nanocomposite

Abstract The nanocomposite of BiVO4-based material has been synthesized by one-step solvent method. The morphological, physical, chemical properties of the nanocomposite have been investigated. The results revealed that the surface area of BiVO4, BiVO4/SiO2 and BiVO4/SiO2/GO was 11.13, 28.47 and 43....
