Photocatalytic Properties of Silver Oxide Loaded on Bismuth Vanadate
In order to enhance the photocatalytic activity of BiVO4, the Ag2O loaded on BiVO4 is studied.In this study, Ag2O loaded on BiVO4 was prepared with Bi(NO3)3, NH4VO3 and C6H8O7 as raw materials by sol-gel method.Influences of the sintering temperature and sintering time were studied on photocatalytic activity, crystal composition and molecular structure.The molecules of matter were characterized by FTIR.Both the phase transition in the sintering process and the influence of Ag2O loaded on crystal structure and size of the BiVO4 powder were studied by XRD.The structure of the obtained samples were studied using transmission electron microscopy.The photocatalytic activity Ag2O loaded on BiVO4 in different calcination time and different calcination temperature had been studied through the degradation methyl orange solution.It is found that the BiVO4 photocatalytic efficiency of methyl orange is about 20% when the samples calcined for 4h and calcined at 500℃, the Ag2O loaded on BiVO4 photocatalytic efficiency of methyl orange is doubled.
