The invention discloses a catalyst for preparing maleic anhydride through oxidation of n-butane and a preparation method thereof, and belongs to the technical field of the catalyst. A catalyst promoter X (at least one of silver, ruthenium and rhodium) is added in the catalyst for preparing the maleic anhydride through the oxidation of the n-butane, a V-X dual-active center is formed in the catalyst, the catalyst has lower selective oxidation activity temperature, the reaction of preparing the maleic anhydride through the oxidation of the n-butane can be completed at lower temperature, and higher selectivity and higher yield of the maleic anhydride can be obtained; the catalyst is mainly used for catalyzing selective oxidation reaction of the n-butane so as to preparing the maleic anhydride.
