H3PMo12O40 (PMo) catalyst was immobilized on the animated polystyrene (PS) support as a charge compensating component, by taking advantage of the overall negative charge of [PMo12O40]3-. PMo catalyst was finely and molecularly dispersed on the PS support via chemical immobilization. The PMo-PS catalyst was applied to the vapor-phase oxidation of methacrolein into methacrylic acid, a typical surface-type reaction. The PMo-PS catalyst exhibited higher conversion of methacrolein and higher selectivity for methacrylic acid than the unsupported PMo catalyst. PMo catalyst was finely and molecularly dispersed on the PS support via chemical immobilization.
