Abstract
The present invention provides a method for producing a catalyst comprising an inert carrier an a mixed metal oxide as a catalytically active component supported on the inert carrier, the method comprising the steps of: a) adding organic acid(s) into solvent(s) and salt of each metal component which will form a mixed metal oxide, to prepare a catalyst precursor solution for the mixed metal oxide; b) adjusting pH of the catalyst precursor solution using a basic solution; c) containing the catalyst precursor solution for the mixed metal oxide, of which the pH is adjusted, on the inert carrier, d) removing the solvent(s); and e) calcining the resultant from step d. The catalyst produced by the present method has improved reproducibility, activity and yield, while maintaining a high selectivity.
