Abstract

H₃PMo₁₂O₄₀ (PMo) catalyst was immobilized on the aminated polystyrene (PS) support as a charge compensating component, by taking advantage of the overall negative charge of [PMo₁₂O ₄₀]^3-. It was revealed that PMo catalyst was finely and molecularly dispersed on the PS support via chemical immobilization. The supported H₃PMo₁₂O₄₀-polystyrene (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. It is concluded that [PMo₁₂O ₄₀]^3- species were chemically and finely immobilized on the PS support as charge matching species, and thus, the PMo-PS catalyst showed an excellent oxidation activity in the model surface-type reaction.
