The Nanospace Catalysis Research Unit is involved in the following three major research projects.
Nanospace catalysts development
【Zeolites】
- Development of methods to control and evaluate the position and distribution of heteroatoms (Al, Ti, Ga, Fe, Sn, etc.) in the zeolite framework.
- Elucidation of dominant factors controlling hydrothermal stability of zeolite catalysts and development of aluminosilicate zeolite catalysts with controlled Al distribution with the aim to improve their hydrothermal stability.
- Creation of multifunctional core-shell zeolite catalysts by heterostructured zeolites and analysis of their structure and reaction mechanisms.
- Composition control, heteroatom distribution control and particle morphology control of large pore CON-type zeolite catalysts.
- Development of a new zeolite synthesis method using zeolite as a raw material for zeolite synthesis and expansion of its application in catalytic materials
- Development of novel zeolite-based SCR catalysts: exploration of pore structure, control of ion exchange sites and improvement of hydrothermal stability.
