Mesoporous silica molecular sieves are a kind of unique catalyst support due to their large pore size and high surface area. Several methods have been developed to immobilize heteropolyacids (HPAs) inside the channels of these mesoporous silicas. The mesoporous silica-supported HPA materials have been widely used as recyclable catalysts in heterogeneous systems. They have shown high catalytic activities and shape selectivities in some reactions, compared to the parent HPAs in homogeneous systems. This review summarizes recent progress in the field of mesoporous silica-supported HPAs applied in the heterogeneous catalysis area and preparation of nanostructured metal oxides using HPAs as precursors and mesoporous silicas as hard templates.

“…Functional groups may enhance the interactions of HPA with the support material either by physical forces (i.e. hydrogen bonding and electrostatic interactions) or chemical bonding and allow higher and more stable loading [19,38,39]. Therefore, this strategy is an important extension, since it allows significant modification of physical and chemical properties.…”

“…By this method, HPAs have been successfully immobilized on polymer materials such as poly-4-vinylpyridine, polyaniline, and polystyrene [31][32][33]. HPAs have also been chemically immobilized on aminopropyl-functionalized mesoporous silica [34,35] and mesostructured cellular foam silica through a grafting method [36].…”

Nitrogen-containing mesoporous carbon (N-MC) was synthesized by a templating method using SBA-15 and polypyrrole as a templating agent and a carbon precursor, respectively. The N-MC was then modified to have a positive charge, and thus, to provide a site for the immobilization of [PMo 10 V 2 O 40 ] 5− . By taking advantage of the overall negative charge of [PMo 10 V 2 O 40 ] 5− , H 5 PMo 10 V 2 O 40 (PMo 10 V 2 ) catalyst was chemically immobilized on the N-MC support as a charge-matching component. Characterization results showed that nitrogen in the N-MC played an important role in forming a nitrogen-derived functional group (amine group), and PMo 10 V 2 catalyst was finely and chemically immobilized on the nitrogen-derived functional group of N-MC support. In the vapor-phase selective conversion of methanol, the PMo 10 V 2 /N-MC catalyst showed a higher conversion of methanol than the bulk PMo 10 V 2 catalyst. Furthermore, the PMo 10 V 2 /N-MC catalyst showed a higher selectivity for dimethoxymethane (a product formed by bifunctional oxidation-acid-acid catalysis) and a higher selectivity for methylformate (a product formed by bifunctional oxidation-acid-oxidation catalysis) than the PMo 10 V 2 catalyst. Reaction pathway for selective conversion of methanol to dimethoxymethane over PMo 10 V 2 /N-MC catalyst could be controlled by changing the methanol feed rate.
