摘要：
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.
