摘要：
Nanoparticles of cerium oxide have been synthesized by green precipitation method by the presence of Moringa oleifera leaf extract with a short reaction time of 5 h. Base on XRD analysis confirmed structure crystal of cerium oxide the formation was a cubic. CeO(2)NPs were discovered to have a spherical shape and an average size of 17 nm, as shown in the TEM image. The formation of CeO(2)NPs was furtherly proven by EDX measurement in the presence of high-intensity peaks referred to Ce and O, with no impurities. The result after FTIR analysis of the nanoparticles demonstrates the appearance of Ce-O stretching, as well as the O-N-O bending disappearance. Based on the DRS UV-Vis analysis result, the band gap energy of CeO(2)NPs was found to be 18% lower than the bulky size. The synthesized CeO(2)NPs exhibit a high antimicrobial activity in the range of 15-31 mm zone inhibition. (C) 2021 The Authors. Published by Elsevier B.V.
