H3PMo12O40 catalyst was chemically immobilized on the surface modified CMK-3 (SM-CMK-3) support as a charge compensating component, by taking advantage of the overall negative charge of [PMo12O40]3-. The supported H 3PMo12O40/SM-CMK-3 catalyst was characterized to have high surface area (≈1000 m2/g) and relatively large pore volume (0.83 cm3/g). The H3PMo12O 40/SM-CMK-3 catalyst was applied to the vapor-phase 2-propanol conversion reaction. The H3PMo12O40/SM-CMK-3 catalyst exhibited higher 2-propanol conversion than the unsupported H 3PMo12O40 and the impregnated H 3PMo12O40 on CMK-3. Furthermore, the PMo 12/SM-CMK-3 catalyst showed the enhanced oxidation activity (acetone formation) and the suppressed acid catalytic activity (propylene formation) compared to the other two catalysts. It is believed that [PMo12O 40]3- species were chemically and finely immobilized on the SM-CMK-3 support as charge matching species, and thus, the PMo 12/SM-CMK-3 catalyst showed an excellent oxidation activity.
