Abstract

A method for green synthesis of ZnO/CuO nanocomposite using Theobroma cacao seed bark extract (TBE) has been investigated. ZnO/CuO nanocomposite synthesis aims to decrease a high band gap energy of ZnO. Zn(NO₃)₂ and Cu(NO₃)₂ solutions were used as a precursors. TBE can substitute NaOH as the base source material which contained alkaloids as shown from the phytochemical test. Identification of nanocomposite was characterized by UV–Vis diffuse reflectance spectrophotometry (DRS), Fourier-transform infrared (FT-IR) spectroscopy, scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX), transmission electron microscopy (TEM), X-ray diffraction analysis (XRD) and Fluorescence Spectrophotometer. ZnO/CuO nanocomposite had the band gap energy of 2.3 eV. TEM result showed the size of ZnO/CuO nanocomposite was 20–50 nm.
