Abstract: In this paper the catalytic mechanism of SO /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.

Key words: solid superacid, catalyst, catalyst support, preparation, modification, application
