showed high activity and conversion in the oxida-
tion of benzyl alcohol to benzaldehyde. The catalytic
activity increased as the silver loading increased. The

acetonitriles as solvent, temperature of 80 C, catalyst
amount of 30 mg, TBHP/alcohol molar ratio of 0.25,
Ag loading of 3% were obtained in reflux condition.
It is a useful strategy for the synthesis of aldehydes
or ketones, without the formation of carboxylate com-
pounds. Results also showed that the catalytic activ-
ity of Ag-ZnO nanocatalyst at microwave condition is 23. Chen D, Qu Z, Shen S, Li X, Shi Y, Wang Y, Fu Q and

much higher than that of reflux condition. The reactiv-
ity order of the alcohols examined in this work was that
aromatic alcohols like benzhydrol were more reactive
than aliphatic alcohols. The reusability of the ZnO sup-
ported with silver was ascertained and catalytic perfor-
