Preparation and Characterization of Bentonite Supported Silicotungstic Acid

摘要：

　　In this paper,the bentonite supported silicotungstic acid with Kiggen structure was prepared by the adsorption of silicotungstic acid on the pretreated bentonite.The bentonite supported silicotungstic acid was characterized with IR,XPS and TG/DTA.The effect of acidification and loading time on the loading amount of silicotungstic acid was investigated.The results indicates that bentonite supported silicotungstic prepared with high temperature activation is stable.
