Catalysts for the Selective Oxidation of Methanol
In industry, one of the main catalysts typically employed for the selective oxidation of methanol to formaldehyde is a multi-component oxide containing both bulk Fe2(MoO4)3 and excess MoO3. It is thought that the excess MoO3 primarily acts to replace any molybdenum lost through sublimation at elevated temperatures, therefore preventing the formation of an unselective Fe2O3 phase. With both oxid...
متن کاملSurface Oxide—Support Interactions in the Molecular Design of Supported Metal Oxide Selective Oxidation Catalysts
A series of metal oxides were deposited on the surface of different oxide supports to study the surface oxide support interactions. The dehydrated Raman spectra of the supported metal oxide catalysts reveal the presence and structure of the supported metal oxide phases. The same surface metal oxide species were found on the different oxide supports for each of the supported metal oxide systems....
متن کاملSelective oxidation of methanol to dimethoxymethane over bifunctional VO(x)/TS-1 catalysts.
This communication describes the design of bifunctional VO(x)/TS-1 catalysts with enhanced redox and acidic character via doping SO(4)(2-) and PO(4)(3-) for selective oxidation of methanol to dimethoxymethane. Redox sites enable the production of formaldehyde, while acidic sites favor the condensation of formaldehyde to DMM.
متن کاملThe electronic factor in alkane oxidation catalysis.
This article addresses the fundamental question of whether concepts from semiconductor physics can be applied to describe the working mode of heterogeneous oxidation catalysts and whether they can be even used to discriminate between selective and unselective reaction pathways. Near-ambient-pressure X-ray photoelectron spectroscopy was applied to the oxidation of n-butane to maleic anhydride on...
