Photocatalytic Properties of Ag@AgCl-RGO Composites

摘要

Ag@AgCl-RGO composite photocatalyst with both graphene's special electronic state structure and Ag@AgCl's excellent visible light catalytic performance was fabricated. Phase composition of the photocatylst were characterized using X-ray diffraction. Scanning electron microscope and UV-vis absorption spectra characterize the surface morphology and spectroscopic properties. The RhB dye concentration was measured by UV-Vis spectra with the changes , the catalytic performance of different photocatalyst was tested, the mechanism of Ag@AgCl-RGO catalyzed degradation of RhB was explored in the presence of the catalyst The research results show that the visible light absorption capacity and catalytic efficiency of Ag@AgCl-RGO was better than Ag@AgCl.
