摘要

In this study, the aerobic oxidation of alkylbenzenes and alcohols in the presence of a novel kind of NiO/Al2O3 nanocatalyst was investigated. The NiO/Al2O3 nanocatalyst was synthesized by the co-precipitation procedure and it was characterized by various techniques, including XRD, FE-SEM, EDS, BET, and TGA. In the presence of the NiO/Al2O3 nanocatalyst, the selective aerobic oxidation of various alkylbenzenes to the corresponding ketones was carried out in water under reflux conditions. Moreover, the selective aerobic oxidation of alcohols to the corresponding aldehydes and ketones was efficiently performed under similar conditions. In both reactions, the results showed that the catalyst was recyclable for up to six consecutive runs through simple filtration.
