Open publisher page 0 citations

Abstract

In this paper,the photocatalytic mechanism of SO2-4/MxOy solid superacid catalyst is discussed.The preparation methods and their characters are discribed,including precipitation impregnation,sol-gel and Hydrothermal.Advances in modifications of the catalysts are analysed,including the studies on carriers and accelerants.Meanwhile its application for wastewater treatment is reviewed.Finally,the development trends of solid superacid photocatalysts are predicted.
