Abstract

Nanocomposites consisting of cerium based nanoparticles stabilized by carboxymethyl cellulose (CMC) macromolecules were obtained using one-pot reaction at room tempera-ture. The characterization of the nanocomposites was carried out with the use of combina-tion of microscopy, XRD and IT-spectroscopy analysis. The type of crystal structure of in-organic nanoparticles corresponding to CeO2 has been determined and the mechanism of the nanoparticles formation was suggested. It was demonstrated that the size and shape of nanoparticles in the resulting nanocomposites does not depend on the ratio of the ini-tial reagents. Spherical particles with mean diameter 3 nm were obtained in different reac-tion mixtures. The scheme of the dual stabilization of CeO2 nanoparticles with carboxylate and hydroxyl groups of CMC. These findings are promising for the development and ap-plication of Ce-based nanoparticles materials.
