Abstract

Mesostructured cellular foam (MCF) silica was synthesized via surfactant templating route. The surface of MCF silica was then modified by grafting 3-aminopropyl-triethoxysilane (APTES) to have the positive charge, and thus, to provide sites for the immobilization of H₃PMo₁₂O ₄₀ (PMo₁₂). By taking advantage of the overall negative charge of [PMo₁₂O₄₀]^3-, PMo₁₂ catalyst was chemically immobilized on the amine-functional group of surface modified MCF (SM-MCF) silica as a charge matching component. It was found that pore structure of MCF silica was maintained even after the surface modification and the subsequent immobilization of PMo₁₂. It was also revealed that PMo₁₂ species were finely and molecularly dispersed on the SM-MCF silica via chemical immobilization.
