Abstract
Ag-modified CaBiO2Cl photocatalysts were synthesized by the one-step solid state reaction method. The microstructure and morphology of catalysts were characterized by using X-ray diffraction, Scanning electron microscopy, and Energy dispersive X-ray detector (EDS) techniques. The photocatalytic activities of pure CaBiO2Cl and Ag-CaBiO2Cl catalysts were further evaluated by degrading methylene blue (MB) under visible-light irradiation. The measured UV-vis absorption spectra indicated that the degradation of Ag-modified CaBiO2Cl has been improved by about 12% in comparison with pure CaBiO2Cl. The enhanced photocatalytic activity in Ag-modified CaBiO2Cl can be ascribed to the better morphologies of the composites due to the Ag additive.
