Abstract
The present invention relates to a catalyst for partial oxidation and a preparation method thereof, more particularly to a preparation method of a complex metal oxide catalyst that shows high activity for conversion of propylene or isobutylene, maintains good selectivity for such unsaturated aldehyde as acrolein or methacrolein and improves production yield of such unsaturated carboxylic acid as acrylic acid or methacrylic acid through stable process by using a drying control chemical additive.
