Abstract: SO42-/MxOy solid superacid catalysts have many advantages such as high activities,less pollution,no corrosion to reactor and easy recycle,so they are a type of typical eco-friendly catalysts. The effects of four preparation methods of impregnation,sol-gel,low-temperature aging and ultrasonic coprecipitation on the catalytic performance of the catalysts were discussed. The research progress in the modification of support and active component of SO42-/MxOy solid superacid catalysts was reviewed. According to the structural model of solid superacid catalysts,the mechanism of acid formation of SO42-/MxOy solid superacid was analyzed. The deactivation mechanism,characterization methods and some application examples of the catalysts were introduced. Finally,the structure theory and preparation technology of SO42-/MxOy solid superacid catalysts were prospected.

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