DEVELOPMENT OF INORGANIC CONDENSED PHOSPHATE CATALYSTS FOR DECOMPOSITION OF GLOBAL WARMING GAS

Abstract

Aluminum and nickel ortho- and condensed phosphates were used as a catalyst for decomposition of trifluoromethane and nitrogen trifluoride. The specific surface area, acid strength, and amount of acidic sites of phosphates were also estimated. The condensation degree of phosphates, the addition of other metal cation, and the reforming by mechanical treatment were discussed on the catalytic activity of the phosphates for the design of catalyst.
