In this paper the catalytic performance of a Co/Al₂O₃ nanocatalyst is investigated on aerobic oxidation of alcohols in a water media at reflux condition. The catalyst was synthesized via a co-precipitation method and characterized by XRD, BET surface area, atomic absorption spectroscopy, SEM, TEM and EDS analysis. The catalyst exhibited a high efficiency on the oxidation of various alcohols into their corresponding carbonyl compounds at relatively short reaction time. Also the results exhibit a consistant activity after several consecutive runs of reaction and regeneration that demonstrates the stability and recyclability of the Co/Al₂O₃ nanocatalyst.

本文研究了Co / Al ₂ O ₃纳米催化剂在回流条件下在水介质中对酒精进行好氧氧化的催化性能。通过共沉淀法合成催化剂，并通过XRD，BET表面积，原子吸收光谱，SEM，TEM和EDS分析进行表征。该催化剂在相对短的反应时间内就将各种醇氧化成其相应的羰基化合物显示出高效率。同样，结果在反应和再生的几个连续运行之后表现出一致的活性，这证明了Co / Al ₂ O ₃纳米催化剂的稳定性和可循环性。
