address: vvk@catalysis.ru (V.V. Kaichev). A B S T R A C TThe methanol oxidation over highly dispersed vanadium oxide supported on TiO 2 (anatase) has been investigated by in situ Fourier transform infrared spectroscopy (FTIR), near ambient pressure X-ray photoelectron spectroscopy (NAP XPS), X-ray absorption near edge structure (XANES), and temperature-programmed reaction spectroscopy. The data were complimented with kinetics measurements in a flow reactor. It was found that at low temperatures dimethoxymethane competes with methyl formate, whereas the production of formaldehyde is greatly inhibited. FTIR shows the presence of non-dissociatively adsorbed molecules of methanol, as well as adsorbed methoxy, dioximethylene, and formate species under reaction conditions. According to the NAP XPS and XANES data, the reaction involves the reversible reduction of V 5+ cations, pointing that the vanadia lattice oxygen participates in the methanol oxidation through the classical Mars-van Krevelen mechanism. The detailed mechanism of the methanol oxidation on vanadia catalysts is discussed.

“…DMM has also been used as a solvent in pharmaceutical and cosmetic industries due to its low toxicity [3]. Furthermore, hydrogen production by reforming of DMM for fuel cell has been recognized as a clean and compact process, because of high hydrogen content and nonpoisonous property of DMM [4]. Easy handling and storage nature of DMM under atmospheric pressure also makes it a good candidate as a hydrogen source for fuel processor [4].…”

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.
