摘　　要：概述了SO42-/MxOy型固体超强酸催化剂的催化机理;分析比较了纳米技术法、低温陈化法、沉淀–混合共沉淀浸渍法、浓硫酸活化钛白粉法等制备出的催化剂对催化性能的影响;介绍了催化剂载体改性、引入金属或离子、促进剂等改性方面的研究进展;展望了固体超强酸催化剂的研究和应用前景。In this paper the catalytic mechanism of SO4^2-/MxOy solid superacid catalyst was summarized, and the effects of the preparation methods, including nano-technique, low-temperature aging, coprecipitation impregnation, solid titanium oxide, on catalytic activity were analysed. Meanwhile the research progress in modification of catalysts on carriers, metals or ions, accelerants was discribed in detail. Finally the prospects of the research and applications of superacid catalysts were predicted.
