Abstract

CMK-3 was prepared using SBA-15 as a removable templating material, and the surface of CMK-3 was chemically modified to have the positive charge. H₃PMo₁₂O₄₀ (PMo₁₂) was then immobilized on the surface modified CMK-3 (SM-CMK-3) as a charge compensating component, by taking advantage of the overall negative charge of [PMo₁₂O₄₀]^3-. The supported H₃PMo₁₂O₄₀/SM- was characterized to have high surface area (ca. 1000 m²/g) and relatively large pore volume (0.83 cm³/g). In the catalytic oxidation of methacrolein, conversion of methacrolein and yield for methacrylic acid were increased in the order of bulk H₃PMo₁₂O₄₀<H₃PMo₁₂O₄₀/CMK-3<H₃PMo₁₂O₄₀/SM The enhanced catalytic performance of H₃PMo₁₂O₄₀/SM-CMK-3 was due to the fine dispersion of H₃PMo₁₂O₄₀ species supported on SM-CMK-3 via chemical immobilization. The catalyst preparation method suggested in this work was very efficient for the model surface-type catalytic oxidation of methacrolein.
