Synthesis of ZnO/CuO nanocomposites with CNF and Ag by gel sol

Abstract

The synthesis of ZnO/CuO with Carbon Nanofiber (CNF) and Ag nanocomposites have been conducted. Nanocomposites were synthesized using sol-gel method. The nanocomposite products were characterized by SEM, TEM, XRD and DSC. The results of the XRD analysis showed that the CuO-ZnO composite has a nanometer size with the average of 10 nanometer. The SEM-EDX analysis showed that the ZnO has a hexagonal structure whereas the CuO has a monoclinic structure. The importance of impregnating the nanofibers with the precursors has been demonstrated. The hydrazine is a better reducing agent than tannic acid. In this study was synthesized polycrystalline silver as evidenced by XRD. SEM-EDAX analysis indicate presence of oxides, nanofibers and silver.
