A novel and active catalyst Ag/ZnO for oxidant-free dehydrogenation of alcohols

• Synthesis and characterization of small amount of Ag supported on ZnO.
• Nano Ag/ZnO as highly efficient heterogeneous catalyst.
• Nano Ag/ZnO for oxidant-free oxidation.
• Nano Ag/ZnO has been confirmed by various methods.

Nano Ag/ZnO catalysts were prepared by varying load of Ag on ZnO supports using a new and very simple method. The structure of nano Ag/ZnO has been confirmed by various techniques. The Ag/ZnO with 7.4 × 10−5 mol% of Ag has pore size distribution about 2.74 nm and this nano Ag/ZnO is found to be the best catalyst for oxidation of primary and secondary benzyl alcohols into corresponding aldehydes and ketones in oxidant-free at the atmospheric pressure. The influence of various parameters such as: solvent, base, temperature, time of reaction, etc. has been systematically studied on nano Ag/ZnO catalyst.

Synthesis and characterization of nano Ag/ZnO by varying loading of Ag on ZnO support using a new and very simple method has been investigated.Figure optionsDownload as PowerPoint slide
