| Abstract: | In order to prepare visible light catalyst with stable performance,a novel highly efficient Ag6Si2O7/TiO2photocatalyst was prepared by an in-situ deposition method.The surface morphology,crystalline structure,chemical elemental composition and fluorescence spectrum of the photocatalyst were analyzed.The photocatalytic activity of the composite catalyst with different concentration of TiO2were tested by degrading methylene blue(MB)under simulated visible light at room temperature.The results show that Ag6Si2O7are coated on TiO2uniformly,Ag6Si2O7and TiO2are tightly bonded in the form of core-shell structure,and Ag+,Si4+and Ti4+exist in composite catalyst.The results of photocatalytic degradation of MB show that the Ag6Si2O7/TiO2photocatalyst exhibits higher photocatalytic activity under visible light than Ag6Si2O7and TiO2used separately.When the mass fraction of TiO2is 20%,the photocatalyst possesses the highest photocatalytic activity.The degradation efficiency for MB is up to 98.6%after irradiating in simulated solar for 20 min.The novel high-efficiency Ag6Si2O7/TiO2photocatalyst has a broad application prospect in treatment of printing and dyeing wastewater. |
