Fields of study	Porous materials, Catalysis, Hydrogen isotope Hydrogen Isotope Science for Environment
Present subjects	1. Tritium enrichment 2. H/D/T separation 3. Catalytic CH4 transformation
About Research	We have found that mesoporous silicas (MCM-41 and SBA-15) show larger tritium adsorption ability and separation factor as compared to the conventional microporous zeolites. These properties for tritium enrichment could be improved by organically functionalization. Separately, we are preparing the hydrogen-isotope exchange catalyst for tritiated water treatment in large scale. We are also challenging the catalytic CH4 conversion to valuable hydrocarbons.
