“…Methyl formate is mainly synthesized by dehydrogenation of methanol over Cu-based catalyst at higher temperatures. 27 In order to know more about the reactivity of MF in the present work, we examine its photocatalytic decomposition over TiO 2 and Pt metals supported by TiO 2 . Attempts will be made to decompose methyl formate in visible light using catalysts of smaller bandgap.…”

“…Methyl formate has been considered as a precursor in the synthesis of formamide, dimethyl formamide, acetic acid, propionic acid, cyanhydric acid, and several other materials; 27 therefore, its efficient production represents technological importance. Methyl formate is mainly synthesized by dehydrogenation of methanol over Cu-based catalyst at higher temperatures.…”

The photoinduced vapor-phase decomposition of methyl formate was investigated on pure and on Pt-metals-promoted TiO 2 . Infrared spectroscopic studies revealed that illumination induced the dissociation of molecularly adsorbed methyl formate to formate on pure TiO 2 even at ∼186 K. This process is indicated by the appearance of the absorption band at 1580−1590 cm −1 due to asymmetric stretch of formate species. The extent of the dissociation is increased with the time of irradiation. Deposition of Pt metals on TiO 2 only slightly influenced this process. The photocatalytic decomposition of methyl formate vapor on pure TiO 2 occurred to only a limited extent at 300 K, but the deposition of Pt metals on TiO 2 appreciably enhanced the extent and the rate of photodecomposition. Nevertheless the photocatalytic reaction of methyl formate proceeded more slowly compared to that of formic acid on the same catalysts, and produced more CO. Addition of H 2 O to the methyl formate decreased the CO/H 2 ratio by a factor of 4. When the bandgap of TiO 2 support was lowered by N-doping from 3.02 to 1.98 eV, the photocatalytic activity of metal/TiO 2 catalysts appreciably increased, and the decomposition of methyl formate was observed even in visible light.

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.

It could be considered as an alternative source of CO/H 2 mixture in the future because of one more CO in its molecule rather than methanol [18,19]. The major industrial application of MF is in producing formic acid by hydrolysis and synthesis of formamide via aminolysis by ammonia.…”
