The aim of this work is to elaborate nanostructured cerium dioxides for catalytic and gas sensor applications. Nanosized cerium oxide powders were prepared via three chemical routes: 1) chemical precipitation followed by high-energy mechanical milling; 2) soft chemical preparation, 3) an unusual method of pulverization of liquid solution developed in our laboratory. The obtained powders were characterized using X-Ray diffraction analyses and Transmission Electron Microscopy experiments. Nanoparticles of pure CeO2 oxide having their sizes ranging from 2 to 10 nanometers have been obtained.
