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.
