The invention relates to a preparation method for an oxide catalyst, and an oxide catalyst prepared by the same, particularly relates to a catalyst for preparing (methyl)acrolein and (methyl)acrylic acid, and relates to a preparation method and an application of the catalyst. The composition of the catalyst is Mo12WaBibFecCodNieCrfCegAhOx/B, wherein A represents at least one of alkali metals of Li, Na, K, Rb and Cs; B is a carrier and is at least one selected from monatomic silicon powder, silicon carbide powder, quartz powder, corundum powder, silicon nitride and boron nitride; and a, b, c, d, e, f, g, h and x represent the number of atoms. By adding a molding assistant in the preparation process, the strength of the catalyst is greatly enhanced. Besides, the assistant can be removed in subsequent roasting step, so that pollution toward the catalyst can be prevented. The catalyst has high activity and good selectivity, and is suitable for long-time cycle use of an apparatus.
