Abstract

PURPOSE: To obtain a highly active catalyst having uniform water repellency and moderate specific surface areas by depositing noble metals on partially fluorinated carbon powder as a catalyst for exchange reaction of water-hydrogen isotope.
CONSTITUTION: In a catalyst for exchange reaction of water-hydrogen istope, noble metals such as rubidium, platinum or the like are deposited on partially fluorinated carbon powder such as fluorinated graphite. The carrier is provided with uniform water repellency microscopically or macroscopically and moderate specific surface areas, and the catalyst particularly effective for concentrating hydrogen isotope is obtained.
