| 摘 要： | 利用硼氢化钠还原法制备出Au-Pd/ZrO2负载型双金属纳米催化剂,采用XRD、UV-vis DRS、TEM等手段对催化剂的结构、吸光能力、粒度、形貌等性能进行表征。结果显示,金、钯成功负载于二氧化锆上,且金、钯以球形颗粒均匀分散。可见光照射下,研究了Au-Pd/ZrO2双金属纳米催化剂对苯甲醇氧化生产苯甲醛反应的适宜条件。实验结果显示,可见光照射下,反应时间为12 h、反应温度为（35±3） ℃、5.0 mL异丙醇为溶剂、50 mg Au-Pd（2:1）/ZrO2为催化剂、1.0 mmol氢氧化钾为碱源的条件下,苯甲醇氧化生产苯甲醛产率最佳。

| Abstract: | Au-Pd/ZrO2 supported bimetallic nanocatalysts were prepared by the reduction method of NaBH4.The structure,absorbance,particle size and morphology of the catalysts were characterized by means of X-ray diffraction（XRD）,UV-vis diffuse reflectance spectroscopy（UV-vis DRS） and transmission electron microscopy（TEM） etc..The results indicated that the Au and Pd were loaded on ZrO2 successfully,and Au and Pa were uniformly dispersed as spherical particles.Under visible light irradiation,the suitable conditions were studied for the oxidation of benzyl alcohol to benzaldehyde by Au-Pd/ZrO2 bimetallic nanocatalysts.The experiment results showed that the best yield of oxidation preparing benzaldehyde by benzyl al-cohol was obtained,under the conditions as follows：visible light irradiation,reaction time of 12 h,reaction temperature of （35±3） ℃,isopropanol of 5.0 mL as the solvent,Au-Pd（2:1）/ZrO2 of 50 mg as the catalyst and NaOH of 1.0 mmol as the basic source. |
