Biofabrication and structural characterization of cerium oxide nanoparticles

Abstract

Cerium oxide synthesis (CeO 2 ) nanoparticles were studied using a new and simple, eco-friendly process. The cerium oxide nanoparticles are synthesized with precursors of ammonium cerium nitrate and sodium hydroxide. Their chemical and physical properties are characterized by energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Fourier transforming infrared spectroscopy (FTIR), and UV-Vis spectrophotometer scanning electron microscopy (SEM), high-resolution electron transmission microscopy (HRTEM). XRD analysis indicated the cubic structure of the nanoparticles containing cerium oxide. The standard particle size of CeO 2 was determined at 30 nm using HR-TEM and XRD. SEM determine the surface morphology of biosynthesized cerium oxide nanoparticles. A Ce-O stretching mode was defined by the strong peaks in the FTIR range, and the peak of UV-Vis range absorbance revealed the 3.26 eV band energy difference.
