Abstract
The present invention relates to a method for preparing a catalyst for partial oxidation of acrolein, particularly to a method for preparing a catalyst for partial oxidation of acrolein that has a superior acrolein conversion rate, acrylic acid activity, selectivity, and yield, by introducing a base solution and an acid solution into a catalyst suspension prepared by dissolving salts of metal ingredients of the catalyst in water to control the acidity of the catalyst suspension, contacting the catalyst suspension of which acidity is controlled with an inert support to support the catalyst thereon, and then drying and firing the supported catalyst.
