Herein, we have developed a nanocomposite catalyst for organic transformation. The catalysts are synthesized based on CuO/ZnO/ZrO materials through the coprecipitation method followed by calcination in air at 500 °C for 5 h. The physicochemical characterization using TGA, XRD, SEM and N -physisorption at -196 °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.
在此，我们开发了一种用于有机转化的纳米复合催化剂。这些催化剂基于CuO/ZnO/ZrO材料通过共沉淀法合成，随后在空气中于500 °C煅烧5小时。对所有制备的催化剂进行了使用TGA、XRD、SEM和在-196 °C下的N-物理吸附的物理化学表征。在所有其他研究的催化剂中，Cu/Zn = 1 : 1的纳米复合催化剂显示出最小的粒径和最大的表面积。在理想的反应条件下，这种新型多相催化剂已证明其对苄醇氧化具有优异的催化效果，并且可以成功地用于多达三个催化循环，而催化活性几乎没有损失。
