A modified catalyst composed of heteropoly compound and α-Sb_2O_4 with oxygen spillover effect was used for the selective oxidation of t-butanol (isobutylene). Methacrylic acid (MAA) was the main product by one-step process. By optimizing the conditions of catalyst preparation and oxidation reaction, the yield of MAA is 50% and the total yield of MAA and methacrolein (MAL) is above 75%. The catalyst revealed a od potential application in industry. The physicochemical characterization of the catalysts (DTA, IR, and XRD) has been reported and the influence of preparation condition on catalytic activity has been examined in this paper.
