摘要：

0.5%Au supported on gamma-AlOOH and gamma-Al2O3 was used for low temperature oxidation of CO and aromatic alcohols. Various characterization techniques, including X-ray diffraction, N2 adsorption, FT-IR spectroscopy, XPS, TEM, CO2-TPD and solid-state MAS NMR, were employed to characterize these catalysts. The Au/gamma-AlOOH sample has abundant hydroxyl groups and basic sites on its surface, exhibiting strong adsorption for aromatic alcohols, and outstanding activity for low-temperature oxidation of aromatic alcohols. The Au/gamma-Al2O3 sample shows sufficient Au+ sites leading to high performance for low-temperature CO oxidation.
