抄録

The most stable perfluorocarbon, CF<SUB>4</SUB>, was decomposed to CO<SUB>2</SUB> at above 550 °C in the presence of water vapor over AlPO<SUB>4</SUB> in which 10 atomic % of Al ions are substituted by Ce. Catalytic activity slightly decreased within first 50 h and then took a stationary state for succeeding 50 h. No changes in the structure of catalyst were observed after 100 h reaction. Mg pyrophosphate and phosphates of Ca, B, Fe, Zn, Bi, and Ni were not active up to 700 °C. The addition of Ce, La, Pr, Nd, Gd, Yb, Er, or Y into AlPO<SUB>4</SUB> increased the catalytic activity.
