The role of oxygen species in the selective oxidation of methanol to dimethoxymethane over VOx/TS-1 catalyst

VOx-based catalysts showed good performance in selective oxidation of methanol to dimethoxymethane (DMM). For VOx/TS-1 catalyst, the experiments of Temperature Programmed Surface Reaction (TPSR), in situ Infrared spectrometer (in situ IR) and X-ray photoelectron spectroscopy (XPS) were carried out to investigate the products distribution of the methanol oxidation reaction and the adsorb-desorption process at active centers. Furthermore, the role of oxygen species during the reaction process over VOx/ TS-1 catalyst and the surface reaction mechanism was explored.
