| 简介 |
Mixed oxides catalysts usable in particular in the full oxidation to CO2 and H2O of volatile organic compounds (VOC), in the decomposition of nitrogen protoxide to nitrogen and oxygen and the combustion of CO, H2 and CH4 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. |
