日本ゼオライト学会　刊行物 Publication of Japan Zeolite Association

I have engaged in the research of zeolite over thirty years. My works cover the adsorption, reactivities of the framework (isotope exchanges between C¹⁸O₂ and frameworks), determination of the ordered distribution of Al atoms in the framework and its relations to properties of zeolites. In this paper, these are reviewed, and some problems under investigation and important future issues are described.
