Study of the Progress of Solid Superacid Photocatalysts in Wastewater Treatment

讨论了SO42-/MxOy型固体超强酸光催化剂的催化机理.叙述了沉淀-浸渍法,溶胶-凝胶法和水热法等制备方法及其特点.介绍了光催化剂在改性方面的研究进展,探讨了其在废水处理方面的应用.最后对固体超强酸光催化剂的研究进行了展望.

In this paper, the photocatalytic mechanism of SO4^2- / MxOy solid superacid catalyst is discussed. The preparation methods and their characters are discribed, including precipitation impregna- tion, 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.
