| 英文摘要 | mesoporous tio2 (meso-tio2) with sharp pore size distribution was synthesized by hydrothermal method. the obtained meso-tio2 is in pure anatase phase and presents spheric aggregates with diameter of 1.0-1.5 mu m, which consists of nanoparticles with size of 6-10 nm. au supported on meso-tio2 (au/meso-tio2) was prepared by urea deposition-precipitation method using haucl4 as gold source. the catalyst was characterized by x-ray diffraction, n-2 adsorption, transmission electron microscopy and uv-vis diffuse reflectance spectroscopy. the catalytic performance of au/meso-tio2 was studied in the oxidation of 1-pentanol to n-valeric acid with molecular oxygen as oxidant in water under basic conditions. it was found that meso-tio2 is a better support for gold catalyst in the oxidation of 1-pentanol than nay zeolite, hydrotalcite, and nano-tio2. deposition-precipitation time, calcination temperature and au loading affected the catalytic performance of au/meso-tio2. the catalyst can also effectively catalyze the oxidation of aliphatic (c-3-c-10) and aromatic alcohols to the corresponding carboxylic acids.
