Abstract

A paradigm shift in the preparation of nanoparticles from a chemical synthetic route to the green synthetic method using plant extractives has gained much impetus. This study used Chromolaena odorata leaf extract to prepare zinc oxide nanoparticles (ZnONPs). The ZnO-NPs were characterised by spectroscopic, optical and thermal techniques. Thermogravimetric Analysis (TGA) revealed no significant weight loss observed after 550°C for precursor powder which was further calcined using a furnace at 800°C and 900°C to obtain ZnO-NPs. Fourier Transform Infrared Spectroscopy (FTIR) spectroscopy analysis indicated Zn-O stretching between 400 cm-¹ to 500 cm-¹. UV-Vis spectra show a strong absorption band at 388 nm for both calcination temperatures. Scanning Electron Microscopy (SEM) images showed the irregular shapes of the samples at different calcinations. The X-ray diffraction (XRD) diffractograms showed that the synthesised ZnO-NPs are in a hexagonal wurtzite structure. Studies of the electrochemical performance showed that ZnO-NPs made with Chromolaena odorata extract and calcined at 800°C have better cyclability than ZnO-NPs calcined at 900°C. Due to better cyclability, these ZnONPs can be applied as anode material in sodium-ion batteries.
