Abstract:
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.
Introduction:
Miki Niwa was born in March 1946 in Aichi, Japan. He received his B. S., M. S., and Ph. D. degrees in applied and synthetic chemistry, from Nagoya University, working with Professor Yuichi Murakami. After studying in Nagoya University as assistant professor and lecturer, he was appointed a professor of Tottori University in 1992. He retired in 2011, and now is working as senior researcher of Nagoya Industrial Science Research Institute, guest professor of Aichi Institute of Technology, visiting professor of National University of Singapore. He has received the Catalysis Society of Japan Award for 2003 and the Japan Petroleum Institute Award for 2007. His research interest is mainly on the catalyst and catalysis of zeolites and metal oxides.
