Preparation and Photocatalytic Performance of RGO/TiO₂ Photocatalyst

Abstract:

In this study, reduced graphene oxide and Titanium dioxide (RGO/TiO₂) photocatalysts were synthesized by ultrasonic mixing. The prepared RGO/TiO₂ photocatalysts were characterized by scanning electron microscopy, X-ray diffraction spectroscopy and UV-visible spectrophotometry. The performance of the RGO/TiO₂ photocatalysts was studied under UV and visible light evaluated by the degradation of the methylene blue (MB). In the photocatalytic process, all the RGO/TiO2 photocatalysts showed better photocatalytic activity than commercial TiO₂ nanopowder (P25) under visible light, which showed that RGO could reduce electron-hole recombination on the TiO_2,led to the improvement of the photocatalytic performance under visible light
