Oxidation catalysts supported on substrates for the decomposition of CO and volatile organic compounds, in particular halogenated organic compounds, at temperatures from 250 ° C to 450 ° C from exhaust streams are described. The oxidation catalyst comprises a refractory oxide such as a solid solution of CeO 2 and ZrO 2 , and a platinum group metal, at least two of which are supported on tin oxide and / or silica, either of which is platinum or ruthenium. |
