Benzylic Alcohol Oxidation using Copper Oxide/ZincOxide/Zirconia Nanocomposite Catalysts

Herein, we have developed a nanocomposite catalyst for organic transformation. The catalysts are synthesized based on CuO/ZnO/ZrO2 materials through the coprecipitation method followed by calcination in air at 500 degrees C for 5 h. The physicochemical characterization using TGA, XRD, SEM and N-2-physisorption at -196 degrees C was carried out for all the prepared catalysts. Nanocomposite catalyst with Cu/Zn=1 : 1 showed the smallest particle size and largest surface area among all the other investigated catalysts. Under ideal reaction conditions, this new heterogenous catalyst has demonstrated its excellent efficacy for the oxidation of benzylic alcohol and can be successfully used in up to three catalytic cycles with little loss of catalytic activity.

Automated summary

A nanocomposite catalyst based on CuO/ZnO/ZrO2 materials was developed using the coprecipitation method and subsequent calcination. The catalysts were characterized using TGA, XRD, SEM, and N-2-physisorption analysis. The nanocomposite catalyst with a Cu/Zn ratio of 1:1 exhibited the smallest particle size and largest surface area. It demonstrated excellent efficacy for the oxidation of benzylic alcohol under optimal conditions and could be used for up to three catalytic cycles with minimal loss of activity.
