Abstract

A catalyst material for the oxidation and/or oxidative dehydrogenation of hydrocarbons, in particular for the selective oxidation of propane to acrylic acid, is specified, comprising a) molybdenum (Mo), b) vanadium (V), c) niobium (Nb), d) tellurium (Te), e) nickel (Ni), f) tungsten (W) and g) manganese (Mn), in which the molar ratio of at least one element, which is selected from nickel, tungsten and manganese, to molybdenum lies in the range 0.01 to 0.2, more preferably 0.05 to 0.15 and particularly preferably from 0.0025:1 to 0.3:1. Furthermore, a catalyst for the oxidation and/or oxidative dehydrogenation of hydrocarbons, a use of the catalyst material or of the catalyst, a method for producing a catalyst material for the oxidation and/or oxidative dehydrogenation of hydrocarbons and a method for the selective oxidation of propane to acrylic acid is specified.
