In the current study, Fe3O4@Al2O3 nanoparticles were successfully synthesized through the simple and cost effective co-precipitation method and were characterized using XRD, SEM, and FT-IR analysis. Since, oxidation of alcohols is one of the most fundamental and challenging processes in organic chemistry, therefore; Fe3O4@Al2O3 nanoparticles were applied as the catalyst for oxidation of alcohol. Besides, the effects of several oxidation reactions parameters such as catalyst concentration, type of solvents, and reaction temperature were studied on the oxidation percentage through the analysis of variance (ANOVA). In addition, recyclability of as-synthesized Fe3O4@Al2O3 catalyst was studied which demonstrated that Fe3O4@Al2O3 nano catalyst could be reused up to five runs without any significant loss of activities. The oxidation results indicated that Fe3O4@Al2O3 nano catalyst provides a high oxidation yield of 91%.
