Abstract
Well monodispersed and large-scaled ceria nanowires with cubic fluorite structure and high aspect ratios were successfully prepared at 80 °C without further sintering via a facile surfactant-assisted alcohothermal route. The X-ray diffraction, transmission electron microscopy with selected-area electron diffraction indicated that the as-prepared ceria nanowires had a cubic fluorite-structure and the morphologies of the products were uniform, with diameters of about 50–100 nm. The TG-DTA and XPS measurements revealed the existence of both trivalent and quadrivalent cerium and an oxidization process took place gradually with increase of the reaction time. Compared with as-reported method, the present process is more convenient and feasible.
