- W2059545925 abstract "The selective oxidation of propane to acetone and 2-propanol with H2 and O2 was studied on Au/TS-1 by kinetic and spectroscopic analysis. A kinetic study using a factorial design at conditions where the catalyst was stable and gave propane conversions of <6% and combined oxygenates selectivity of >90%, resulted in a power-rate law expression of the form roxyg. = koxyg.(H2)0.74(O2)0.36(C3H8)0.29. In situ Au L3-edge X-ray absorption near-edge spectroscopy (XANES) measurements showed activation of O2 on Au, whereas in situ ultraviolet–visible (UV–vis) spectroscopy evidenced the presence of Ti-hydroperoxo species. The role of the Ti-hydroperoxo species was probed by a transient technique in which changes in Ti K-edge XANES spectra were used to determine the evolution of coverage with time (dθ/dt). It was shown that the rate of reaction by XANES (6.7×10−4s−1) was close to the turnover rate measured in a catalytic flow reactor (5.6×10−4s−1), indicating that the hydroperoxo species were true intermediates in the reaction. A proposed reaction sequence in which H2O2 forms on Au sites and propane is partially oxidized on Ti centers accounts for the spectroscopic results and the reaction orders obtained experimentally for the power-rate law expression." @default.
