Abstract

CeO2 nanoparticles (NPs) were successfully prepared by the precursor of Ce(NO3)2, and Datura metel L. leaves extract (DME) as a source of weak base, and capping agents. CeO2 NPs were characterized by UV–Vis spectrophotometer, FT-IR, XRD, SEM-EDX, and TEM. The CeO2 NPs were formed at the maximum wavelength of 252 nm confirmed by UV–Vis spectrophotometer. CeO2 NPs have a particle size around 5–15 nm with a spherical shape. XRD characterization confirms that CeO2 crystals were analyzed as face-centre cubic. The formed CeO2 NPs were tested for the degradation of 1,1-Diphenyl-2-Picrylhydrazyl (DPPH) as a radical compound. In addition, DPPH was degraded into 1,1-Piphenyl-2-Picrylhydrazine, which was well-known as a non-radical compound signed by the decrease of absorbance at the maximum wavelength of 516 nm and the solution colour changed from purple to colourless. At last, the degradation percentage of DPPH radical using CeO2 NPs was found to be 16.61%.
