| Summary: | In this study, tin oxide nanoparticles (SnO2 NPs) were synthesized via a green protocol using bioactive compounds from Chromolaena odorata leaves which stand as a reducing and capping agent. The leaves underwent two types of grinding techniques to investigate which technique would provide bioactive compounds in effective concentration to assist the biosynthesis process; ball-mill and electronic blender. The prepared SnO2 NPs were characterized by fourier-transform infrared (FTIR), x-ray diffraction analysis (XRD), field emission scanning electron microscopy (FESEM), energy dispersive x-ray spectroscopy (EDX) and UV-visible diffuse reflectance spectroscopy (DRS). FTIR spectra evidenced the pertinent functional groups of SnO2 NPs. From XRD analysis, both samples developed in tetragonal structure whereby ball-mill and electronic blender techniques gave average crystallite size of 7.85 and 11.60 nm respectively. Uniform distribution of agglomerated spherical shape of SnO2 NPs was observed from the FESEM images and EDX analysis confirmed the presence of Sn and O elements. The reflectance percentage of SnO2 NPs was found to be 48% with energy band value of 3.13 eV produced from ball-mill technique, while 37% reflectance and 3.39 eV from latter technique. Band gap values suggested this synthesized SnO2 NPs using both techniques are practical candidates for optical function. © 2021 International Scientific Organization. All Rights Reserved.
