ABSTRACT
The aim of this work is to investigate the capabilities of Uncaria Gambir Leaf Extract (UGLE) in the synthesis of ZnO Nanoparticles (NPs) via a green approach. We made two types of nanoparticles. The first nanoparticles were prepared by dissolving Zn(Ac)2.2H2O in UGLE and the second nanoparticles were prepared by dissolving Zn(Ac)2.2H2O in isopropanol. The ZnO NPs were characterized by Differential Thermal Analysis and Thermogravimetric Analysis (DTA-TGA), Fourier Trasform Infra Red (FTIR) spectroscopy, X-Ray Diffractometer (XRD) and Scanning Electron Microscopy (SEM). The synthesized NPs have a wurtzite hexagonal structure, with the average particle size, as calculated from XRD analysis, being 65 nm and 35 nm, for ZnO NPs without UGLE and with UGLE, respectively. Scanning Electron Microscopy (SEM) analysis revealed a ZnO rod without UGLE and a spherical shape with UGLE.
