Synthesis of CuO-ZnO Nanocomposite for Environmental Applications

(De Gruyter) – Metal oxide nanocomposites have gained attention as catalysts, sensors, hydrogen storage, and optoelectronics. Copper oxide-zinc oxide (CuO-ZnO) is an excellent candidate for advanced materials as it has tunable catalytic, electrical, optical, and magnetic properties as well as being environmentally-friendly nature.

The authors review the synthetic techniques of CuO-ZnO nanocomposite formation and its morphology and evaluate its use in environmental applications.

Different types of CuO-ZnO nanocomposites such as Cu-doped ZnO, Cu supported/impregnated on ZnO, and CuO-ZnO mixed oxides with different morphologies of CuO-ZnO nanocomposites have been obtained previously in the lab. CuO-ZnO nanocomposites have been prepared by various methods including co-precipitation, sol-gel, wet impregnation, and thermal decomposition. However, scaling up to the industrial scale has remained a challenge and requires identifying new methods of control.

Improved knowledge of surface chemistry, methods of morphological modifications, and colloidal synthesis has helped in CuO-ZnO nanocomposite preparation.

The authors found that properties of the CuO-ZnO nanocomposites are highly structure/size and ratio dependent.

Further studies are required to provide better insights into the CuO-ZnO structure-property relationship with more attention to dispersion, size, porosity, rate of synthesis, and cost effectiveness.
