Synthesis of TiO2/BiVO4 Composite and Cogitation the Interfacial Charge Transportation for Evaluation of Photocatalytic Activity

In this study, a facile hydrothermal approach was used to fabricate novel TiO2/BiVO4 composite photocatalysts with heterojunction architectures. The physical and photochemical properties of the as-prepared catalysts were multiple characterized using X-ray diffraction, field emission scanning electron microscopy, Fourier transforms infrared spectrometry, UV-Vis diffuse reflectance spectra, X-ray photon spectroscopy analysis, BET surface area analysis and photoluminescence technique. The photocatalytic performance was assessed by decolorizing methylene blue, methyl orange dye and their mixture solution under visible light irradiation. Compared with pure TiO2 and BiVO4, the TiO2/BiVO4 composites demonstrate greater photocatalytic activity. Enhanced photocatalytic activity is largely owed to the increased separation rate of photogenerated charge carriers.

Automated summary

In this study, TiO2/BiVO4 composite photocatalysts with heterojunction architectures were successfully synthesized by a facile hydrothermal method. The as-prepared catalysts were characterized using various techniques, and their photocatalytic performance was evaluated. The TiO2/BiVO4 composites exhibited enhanced photocatalytic activity compared to pure TiO2 and BiVO4, which can be attributed to the increased separation rate of photogenerated charge carriers.
