Abstract:

WO3 doping TiO2 composites with nanocarbon are prepared by sol-gel and hydrothermal, and the composites are studied by X-ray diffraction (XRD), UV-visible light scanning. The photocatalytic degradation effects of different conditions on the direct scarlet 4BS solution has been Investigated. The results show that doped WO3 does not change the main structure of TiO2, but affect its crystalline properties. When WO3 doping amount is 3.0 mol%, the crystallinity of composite reaches maximum value. The introduction of nanocarbon can improve the crystallinity of composite when the molar ratio of WO3 doping is 3.0%, the photocatalytic activity is the highest, nanocarbon as a carrier can increase the photocatalyst adsorption capacity to achieve the objective of improving the photocatalytic efficiency when WO3 and nanocarbon doped TiO2, the stability of the composite about catalytic activity is excellent.
