英文摘要: Au/NaY was prepared by deposition-precipitation (DP) method using HAuCl4 as gold source. The samples were characterized by X-ray diffraction, N-2 adsorption, transmission electron microscopy and inductively coupled plasma atomic emission spectrometry. It was found that the adjustment of the surface acidity of NaY, the pH and concentration of HAuCl4 solution, and the temperature and time for DP affected the particle size, the loading and the morphology of Au on NaY. The catalytic performance of Au/NaY was studied in the oxidation of alcohols to the corresponding carboxylic acids with molecular oxygen as oxidant under basic conditions. About 100% conversion of benzyl alcohol with 95.2% isolated yield of benzoic acid was obtained at the reaction temperature of 80 degrees C for 8 h. The catalyst was recycled for four times without loss of catalytic activity. In addition, the catalyst worked well for the catalytic oxidation of various alcohols including aromatic and aliphatic alcohols to the corresponding carboxyl acids. (C) 2012 Elsevier B.V.
