Abstract:
1. A process for producing a metal oxide catalyst represented by the following composition formula, which is characterized by allowing a fine particle of metallic tellurium as obtained by reducing a Te 4+ compound or a Te 6+ compound in the presence of a reductant and water or an organic solvent to react in the presence of an Mo compound, a V compound, a compound containing an A element and water and then drying and calcining (wherein A is at least one element selected from Nb, Ta, W, Ti, Zr, Re, Fe, Ni, Co, Sn, Tl, Cu, rare earth elements, and alkali metal elements, i and j are each from 0.01 to 1.5, and j/i is from 0.3 to 1.0; k is from 0.001 to 3.0; and y is the number to be determined by the oxidized state of other elements).
