Adsorption and Photocatalytic Processes of Mesoporous SiO(2)-Coated Monoclinic BiVO(4)

The silicon dioxide (SiO(2))–coated bismuth vanadate (BiVO(4)) composites as visible–driven–photocatalysts were successfully synthesized by the co–precipitation method. The effects of SiO(2) coating on the structure, optical property, morphology and surface properties of the composites were investig...

description The silicon dioxide (SiO(2))–coated bismuth vanadate (BiVO(4)) composites as visible–driven–photocatalysts were successfully synthesized by the co–precipitation method. The effects of SiO(2) coating on the structure, optical property, morphology and surface properties of the composites were investigated by X–ray diffraction (XRD), UV–visible diffuse reflectance spectroscopy (DRS), transmission electron microscopy (TEM) and Brunauer–Emmette–Teller (BET) measurements. The photocatalytic activity of monoclinic BiVO(4) and BiVO(4)/SiO(2) composites were evaluated according to the degradation of methylene blue (MB) dye aqueous solution under visible light irradiation. The SiO(2−)coated BiVO(4) composites showed the enhancing photocatalytic activity approximately threefold in comparison with the single phase BiVO(4).
