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.

Method for preparing a catalyst for partial oxidation of acrolein

The present invention relates to a method for preparing a catalyst for partial oxidation of propylene, particularly a method for preparing a catalyst for preparing an acrylic acid, using an organic acid such as a citric acid, maleic acid and oxalic acid. The complex oxide catalyst according to the invention, when used in the gas phase catalytic oxidation of propylene, may produce acrolein in high yield.
