Abstract

A method for production of vanadium catalysts, including steps of 1) providing a mixture comprising a TiO2-based support and a composite oxide containing vanadium and antimony; 2) preparing a slurry containing the mixture obtained from step 1), and additive comprising at least one species selected from the group consisting of Si, Al, Zr, Ti, W and Mo, and a solvent; and 3) applying the slurry onto a substrate or processing the slurry into shaped bodies. The vanadium catalysts obtained/obtainable from the method, and use thereof for abatement of nitrogen oxides (NOx).
