Abstract
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.
