Abstract

Abstract: In this contribution, it is reported for the first time from literature the possibility of synthesizing CeO2 nanoparticles using entirely new green process. This is in view of using natural extract of Agathosma betulina as a chelating agent at room temperature. The antibacterial activity of CeO2 nanoparticles is therefore, investigated. The high-resolution transmission electron microscopy (HRTEM) and the selected area electron diffraction (SAED) confirmed the polycrystallinity of the CeO2 nanoparticles annealed at various temperatures. X-ray diffraction showed complementary investigations that substantiated the single phase and the elementary purity of the CeO2 nano-scaled particles as shown by the EDS.
