Morphology-Controllable Synthesis of CeO(2)on a Pt Electrode

Nanoscale cerium dioxides with shape of nanoparticles, nanorods, and nanotubes were electrochemically synthesized. The morphology of CeO(2)was modulated by changing electrode potential and potential direction. CeO(2)nanorods and CeO(2)nanotubes were synthesized via the potentiostatic and cyclic volt...

Sumario:Nanoscale cerium dioxides with shape of nanoparticles, nanorods, and nanotubes were electrochemically synthesized. The morphology of CeO(2)was modulated by changing electrode potential and potential direction. CeO(2)nanorods and CeO(2)nanotubes were synthesized via the potentiostatic and cyclic voltammeteric methods, respectively. The morphology and structure of the obtained CeO(2)were characterized by field emission scanning electron microscope (FESEM) and X-ray diffraction (XRD). A possible formation mechanism has been suggested to illuminate the relationship between the preparation condition and the morphology of CeO(2).
