Synthesis of ZnO/CuO Nanocomposite by Ultrasound Assisted Co-Precipitation Process using Rambutan Peel Extract

In this study, ZnO/CuO nanocomposites were synthesized by a ultrasound assisted co-precipitation method. Green synthesis of ZnO/CuO nanocomposite using rambutan peel extract as an efficient stabilizer agent has been investigated. Biosynthesized ZnO/CuO nanocomposites were characterized by X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), field emission electron microscopy (FESEM), energy dispersive X-ray (EDX) and UV-Vis spectroscopy. The FESEM result showed the size of nanocomposite was 30-100 nm and had the band gap ennergy of 2.37 eV.
