NEW METAL HALIDE CATALYSTS FOR REDUCTION OP NITRIC OXIDE WITH AMMONIA

Abstract
The effect of counter anions on the catalytic activities of cupric and ferric ions, when salts of them are used as catalysts for the reduction of nitric oxide with ammonia, was investigated. The order of the co-catalyst activity of the counter anions investigated is Br−, Cl−, SO42−, and O2−.
