Abstract

The most stable perfluorocarbon, CF4, was decomposed to CO2 at above 550 °C in the presence of water vapor over AIPO4 in which 10 atomic % of A1 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 AIPO4 increased the catalytic activity.
