Abstract
Recently, the synthesis of nanomaterials using a green approach has been extensively carried out to lessen the environmental issues caused by chemical methods. This paper presents an eco-friendly synthesis of cerium oxide nanoparticles (CeO2 NPs) employing Terminalia catappa leaf extract. Using a FESEM with energy-dispersive X-rays (EDX), the morphology and elemental composition of the biosynthesized nanoparticles were assessed. UV–visible spectra of the green synthesized CeO2 nanoparticles exhibited a characteristic absorption peak at 320 nm. The nanoparticles were also characterized through XRD and FT-IR spectroscopy. By using dynamic light scattering (DLS) investigations, the hydrodynamic size and zeta potential of the biosynthesized nanoparticles were ascertained. Additionally, bacterial strains were utilized to evaluate the antibacterial efficacy. The biosynthesized nanoparticles can be utilized in drug delivery, wound healing, and catalytic applications. Furthermore, the green synthesis method will reduce the environmental concern over the chemically synthesized nanoparticles.
