Experimental and Theoretical Study of Morphological and Charging Properties of Truncated Octahedron and Cubic Ceria Nanoparticles: Implications for Biomedical Applications

Ceria (CeO2) nanoparticles are known to be very often used in various applications from biomedicine fuel cells. To optimize the applications, detailed information about physicochemical properties such as size, shape, and charge of should available. Therefore, our study we performed a systematic ceria ranging synthesis comprehensive experimental theoretical characterization. We synthesized using two paths which led formation types nanoparticles. The structure charging both were studied by X-ray powder diffraction (XRD), high-resolution transmission electron microscopy (HR-TEM), particle detector (PCD) for surface density, ZetaPlus instrument electrophoretic mobility measurements. results suggested that case where hydrolysis Ce(NO3)3 at room temperature was applied with morphology close spherical, more exactly truncated octahedron synthesized. On other hand, obtained hydrothermal had characteristic cube-like morphology. Finally, complete understanding interpretation system, prepared model based on classical density functional theory electrolyte solutions coupled regulation via law mass action. Even without fitting parameters, adequately describes data. All could serve basis obtaining tuned engineered optimized lead improved nanotechnology biomedical research.
