Abstract

This invention relates to a de-NOx catalyst without containing any reductant in decomposing nitrogen mono-oxide, in which a mixture of zeolite and Al2O3 is subject to drying, calcining and crushing processes to obtain a catalyst carrier. After Pt/Rh or Pd/Rh precious metal solution is added followed by subjecting the carrier to drying and calcining once again, a de-NOx catalyst without using reductant such as ammonia gas and propane can be obtained. The best de-NOx inversion rate occurs under temperatures ranging from 250 DEG C to 500 DEG C. When the polluted air includes CO in addition to No, the de-Nox inversion rate of the de-NOx catalyst of the present invention can also realize fairly good efficacy.
