摘要

用γ-AlOOH和γ-Al2O3负载0.5%Au对CO和芳香醇进行低温氧化。采用x射线衍射、N2吸附、FT-IR、XPS、TEM、CO2-TPD和固态MAS NMR等表征技术对催化剂进行了表征。Au/γ-AlOOH样品表面具有丰富的羟基和碱性位点，对芳香醇具有较强的吸附能力，对芳香醇具有较好的低温氧化活性。Au/γ-Al2O3样品显示出充足的Au+位点，具有良好的低温CO氧化性能。

Au supported on γ-AlOOH and γ-Al2O3 for low temperature oxidation of CO and aromatic alcohols†

0.5%Au supported on γ-AlOOH and γ-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/γ-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/γ-Al₂O₃ sample shows sufficient Au⁺ sites leading to high performance for low-temperature CO oxidation.
