This study explores the synthesis and characterization of silicon oxide nanoparticles (SiONPs) using plantain peels as a sustainable precursor. SiONPs hold immense promise in various fields due to their exceptional attributes, and there is a growing need for eco-friendly synthesis methods. The research addresses this need by using agricultural waste materials, specifically plantain peels, as a renewable and cost-effective source for SiONP production. In the study, plantain peel samples were dried, ashed and converted to Si(OH)2 after a series of reactions with HCl and NaOH respectively. The Si(OH)2 obtained was calcined at 700 °C for two hours. The silicon oxide nanoparticles obtained were characterized with an ultraviolet-visible spectrophotometer, X-ray diffractometer and nitrogen adsorption study based on Brunaer-Emmett-Teller as well as other models. The results obtained showed that the XRD spectrum indicated a principal peak at 69, which was attributed to Si(111) or Si(40). The crystallite size of the silicon oxide nanoparticles obtained from the plantain peels was 0.23 nm while the evaluated particle size was 3.012 nm, confirming a mesoporous dimension. The absorption peaks obtained from the ultraviolet-visible analysis indicated a wavelength of maximum absorption at 342 nm and a corresponding bandgap of 3.6 eV. The materials are regarded as a highly porous semiconductors with unique potentials for environmental, optical, electrical and other applications. These results collectively highlight the eco-friendly synthesis and versatile applications of SiONPs, emphasizing their significance in advancing nanotechnology across diverse industries and scientific disciplines.
