The present invention relates to a method for preparing a catalyst and a method for preparing unsaturated carboxylic acid using the catalyst prepared according to the preparation method. According to the method for preparing a catalyst, unsaturated carboxylic acid can be provided from an unsaturated aldehyde with a high conversion rate and selectivity.

Method for preparing catalyst

The present invention relates to a high-performance polyoxometalate catalyst and a method of preparing the same. More particularly, the present invention provides a high-performance polyoxometalate catalyst, the activity and selectivity of which may be improved by controlling the content of vanadium and the like and which has superior reproducibility and may unsaturated carboxylic acid from unsaturated aldehyde in a high yield for a long time, a method of preparing the same, and the like.
