Fabrication of AgBr/Ag2CrO4 composites for enhanced visible-light photocatalytic activity
Source abstract
Abstract
Abstract Ag 2 CrO 4 and AgBr/Ag 2 CrO 4 photocatalysts were synthesized by a simple precipitation reaction and were compared for their photocatlytic activity. These photocatalysts were characterized by X-ray diffraction, Scanning electron microscopy, Fourier transform infrared spectroscopy and UV–vis diffuse reflection spectroscopy techniques. The photocatalytic performance of the samples was evaluated by photocatalytic oxidation of rhodamine B (RhB) dye under visible-light irradiation. The results indicated that the AgBr/Ag 2 CrO 4 exhibited a higher photocatalytic activity than the pure Ag 2 CrO 4 . The enhancement of photocatalytic activity was related to the stronger light absorption ability and also due to the fact that the insoluble AgBr effectively protected the Ag 2 CrO 4 photocatalyst from dissolution in aqueous solutions to enhance its structural stability.
