Abstract

The preparation of Ce(OH)3/CeO2 nanostructures(NSs) through electrogeneration of base into anodicalumina membranes was studied. The effects of solvent(alcohol and/or water), Ce3? partner anion nature (chlorideor nitrate) and concentration, applied potential or currentdensity in driving the morphology toward nanowires(NWs) and/or nanotubes (NTs) was described. The structuralanalysis performed by X-Ray Diffraction and RamanSpectroscopy allowed to evidence that the presence ofCe(IV) into the nanostructures strongly depends on theoxygen content in the growing environment.
