Paper Title:
Preparation and Characterization of Rare Earth Solid Superacids SO42-/TiO2-SnO2-Dy2O3
  Abstract

A new rare earth solid superacids catalyst SO42-/TiO2-SnO2-Dy2O3 was prepared by coprecipitation-impregnating method, and the optimum preparation conditions were obtained. The physic- chemical properties of the catalyst was characterized by FTIR, TG-DTA, XRD and BET. The results showed the prepared catalyst is superacid with good thermal stability and high specific surface area. The sulfuric groups were proved to be chelated and bridgingly connected on the surface of the catalyst.
