PURPOSE:To efficiently, catalytically decompose nitrous oxide in a waste gas even at a low temp. by using a catalyst carrying at least one or more kind of noble metals selected from among Ru, Rh, Pd, Re, Os, Ir, Pt in the coexistence of a reducing gas. CONSTITUTION:The catalyst carrying at least one or more kind selected from among Ru, Rh, Pd, Re, Os, Ir, Pt is used in the coexistence of the reducing gas (e.g. methane). The catalyst is allowed to be carried on a fluorine treated carrier. And the catalyst is allowed to be carried on a hydrophobic carrier. As a result, nitrous oxide in the waste gas is efficiently, catalytically decomposed even at the low temp. |
