　　报告摘要： 

　　His historical overview of the development of ammonia TPD experiment to measure the solid acidity of zeolite is reviewed. Ammonia TPD is controlled by the equilibrium between ammonia molecules in the gas phase and on the surface. The method to measure number and strength of the acid sites of zeolite is precisely explained. In order to overcome the drawback of the method, IRMS-TPD in which not only mass spec but also IR is working together to get the information of the structure of acid site is proposed. We have very detailed information of the acid sites of zeolite using this method. In addition, DFT calculation supports the experimental observations.
