Synthesis and characterization of cubic Ag3PO4 visible light photocatalyst
摘要
Abstract
Cubic silver orthophosphate photocatalyst with good activity was successfully fabricated through a simple silver-ammine assisted method by using AgNO3,Na2HPO4 and NH3 · H2O.X-ray powder diffraction,scanning electron microscopy,Fourier transform infrared spectrometer and UV-vis diffuse reflectance spectrometer were employed to investigate the phase structure,micro morphology and absorbance of Ag3PO4 powders.The photocatalytic activity of Ag3PO4 photocatalyst was tested by the photocatalytic degradation of Rhodamine B aqueous solution under the simulated sunlight irradiation.The results reveal that the asprepared cubic Ag3PO4 crystals are bounded entirely by six of [100] facets and exhibit much better photocatalytic activity than spheres.This is due to the higher absorption efficiency of the visible light photons,effectively separation of electrons and holes and catalytically activesites on their surfaces of cubic silver orthophosphate photocatalyst which is dominated by the highly active [100] facets.关键词
