| 简介 |
Mixed oxides catalysts usable in particular in the full oxidation to CO 2 and H 2 O of volatile organic compounds (VOC), in the decomposition of nitrogen protoxide to nitrogen and oxygen and the combustion of CO, H 2 and CH 4 off gases in fuel cells, comprising oxides of manganese, copper and one or more rare-earth metals, wherein the rare earth metals can assume multiple valency states, having a percentage composition by weight, expressed as MnO CuO and rare-earth oxides, in which the rare earth metal has the minimum valence value, respectively of 35-56%, 19-31% and 20-37%. The oxides are supported on inert porous inorganic oxides, preferably alumina. |
