Abstract
In a composite oxide catalyst, a preparation method therefor, and a use thereof, the catalyst has the following general formula: MoFeaAlbPcOx, wherein a=0.25-0.5, b=0.001-0.2, c=0.001-0.6, and x is a number satisfying the valence of the general formula. The catalyst has excellent low-temperature performance and thus has a long service life.
