Photoinduced-reaction dynamics of halogenated alkanes on iron oxide surfaces: CH3I on Fe3O4(111)-(2*2)

Article Abstract:

The adsorption, thermal chemistry, and photoreaction dynamics of methyl iodide on the (2*2) magnetite termination of natural single-crystal hematite are investigated by various methods, which include temperature-programmed desorption. The methyl iodide thermal desorption spectra, taken after dosing the (2*2) surface at 100K with CH3I, show a multiple-peak coverage-dependent behavior, consistent with the presence of several distinct adsorbed phases.

Selective one-step synthesis of dimethoxymethane via methanol or dimethyl ether oxidation on H(sub 3+n)VnMo(sub 12-n)PO40 Keggin structures

Article Abstract:

Dimethoxymethane (DMM; CH3OCH2OCH3) is an important chemical intermediate used as a gasoline additive and as a building block in organic synthesis. The one-step selective synthesis of dimethoxymethane (DMM; CH3OCH2OCH3) was achieved at low temperatures (453-513 K) on unsupported and SiO2-supported heteropolyacids with Keggin structures H(sub 3+n)VnMo(sub 12-n)O40 (n = 0-4).
