Research Abstract

Room temperature detritiation technology has been researched and developed to enhance the tritium safety of fusion facilities. The inorganic-based hydrophobic Pt-catalyst has been developed for efficient oxidation of hydrogen isotopes at room temperature, even in the presence of saturated water vapor. The zeolite which framework SiO2/Al2O3 ratio is controlled to be 10 is suitable for water absorbent of room temperature dryer due to excellent detritiation and dehydration performance at room temperature.
