The Nanospace Catalysis Research Unit is involved in the following three major research projects.

Nanospace catalysts development

  • 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.
