A series of new superacid catalysts MCM 41 supported SO 2- 4/ZrO 2(SZ) were prepared first by an impregnation calcination method. The variation roles of their texture constructions and acid properties were investigated in detail. It was shown that, a high amount of ZrO 2 could result in the damage of the pore system of MCM 41, however, superacid sites could not formed under a low amount of SZ on MCM 41. The proper amount of SZ is about 40%. The superacidities of samples were increased with the i...
