Catalyst for the reductive conversion of nitrogen oxides, optionally accompanied by sulfur dioxides, in waste gases, produced by the impregnation of a support, for example, a TiO 2 support, with a vanadium alkoxide, and treatment of the impregnated support in the oxygen-containing gas current. The catalyst brings about a conversion of the nitrogen oxides even at a relatively low temperature of 150° to 350° C. |
