Wet Synthesis of Copper Oxide Nanopowder

A simple and efficient synthesis of cuprous oxide and cupric oxide nanoparticles was carried out with controlled surface properties via soft chemistry approach. The monodisperse and versatile Cu2O and CuO nanoparticles were characterized with the help of FT-IR, UV-Vis, TGA/DSC, XRD, SEM-EDX, TEM, and BET. From the XRD analysis, the size of Cu2O and CuO nanoparticles were calculated as 31 nm and 32 nm, respectively, which is calculated with the help of Scherer equation, as supported by TEM. The morphology of the nanoparticles can be controlled by tuning the amount of KOH and nature of solvent. Chemie douce approach is a novel, cheap, and convenient technique suitable for industrial production.
