Characterization of CeO2NPs. (A) TEM of CeO2NPs. (B) Hydrodynamic size change of CeO2NPs aqueous solution. (C) X-ray diffraction (XRD) of freeze-dried powder of CeO2NPs. X-ray photoelectron spectroscopy (XPS) of freeze-dried powder of CeO2NPs and the spectrum of Ce element (D) and O element (E) are divided into peaks. The proportions of Ce3+ and Ce4+ elements and the proportions of lattice oxygen (Lo) and vacancy oxygen (Vo) of O elements are calculated after peak splitting
