Abstract

A catalyst material for the oxidation and/or oxidative dehydrogenation of hydrocarbons, in particular for the selective oxidation of propane to acrylic acid, comprising a) molybdenum (Mo), b) vanadium (V), c) niobium (Nb), d) tellurium (Te), e) manganese (Mn) and cobalt, in which the molar ratio of at least one element, which is selected from manganese and cobalt, to molybdenum lies in the range 0.01 to 0.2. 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.
