Abstract
An efficient, greener, simple approach to synthesize copper oxide nanoparticles using aqueous extract o f r a m b u t a n peel as a precipitant and reducing agent. Green synthesis of copper oxide nanoparticles was found via hydroxide precipitation using rambutan peel wastes. The successful formation of copper oxide nanoparticles was confirmed by UV-Visible, XRD, SEM, TEM and SAED studies. UV-Visible confirms the absorption spectrum of copper oxide around 360nm. X-Ray Diffraction results found the highest intense peak (111) and the average crystallite size calculated as 35.74nm using debye scherrer's formula. Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) images confirm the formation of copper oxide nanoparticles looks flake-like structures and shows the particle size range between 20-50nm. Further Selected Area Electron Diffraction (SAED) pattern also confirms the crystalline nature of copper oxide nanoparticles. F u r t h e r , a p ossible for ma tio n mechanism was pr opo sed fo r CuO nanoparticles using rambutan peel wastes.
