摘要：
Cerium dioxide nanoparticles (CeO2) were synthesized by precipitation in the reversal microemulsions based on different surfactants. Crystallographic properties and morphology of CeO2 nanoparticles were studied by X-ray diffraction method and transmission electron microscopy. It was established that CeO2 nanoparticles synthesized in the reversal microemulsions had sizes in the range of 6-10nm. Zeta-potential values of nanoparticles were measured by dynamic light scattering method and stability of CeO2 in the aqueous suspension was estimated. It was shown that CeO2 nanoparticles formed high-stable aqueous suspensions. It was studied that CeO2 nanoparticles displayed catalase-like activity and they could be promising for development of the antioxidant nanomaterials for treatment of the sequences of oxidative stress.
