PURPOSE: To provide a method for producing a catalyst for the vapor phase oxidation of an alkane to an unsaturated aldehyde or carboxylic acid. CONSTITUTION: (A) Metallic compounds (at least one of which is an oxygen- containing compound) and a solvent are mixed to form a solution, (B) the solvent is removed from the solution to obtain a catalyst precursor and (C) this catalyst precursor is calcined in an inert atmosphere at 350-850deg.C to form the objective catalyst of the formula WaVbXxYyOn (where 0.25 < a < 0.98, 0.003 < b < 0.5, 0.003 < x < 0.5, 0.003 < y < 0.5, X is selected from the group comprising Te, Bi, Sb and Se, and Y is selected from Nb, Ta, etc.).
