Preparation of Cerium Dioxide Film by Anodization in Na₂C₂O₄-NH₃∙H₂O-H₂O-(CH₂OH)₂ Electrolyte

Abstract:

The cerium dioxide films were prepared with cerium foils as raw materials by anodization in Na₂C₂O₄-NH₃∙H₂O-H₂O-(CH₂OH)₂ electrolyte. The anodic cerium oxide film was heat treated at 550°C. The cerium dioxide films were characterized with X-ray diffraction (XRD), energy-dispersive analyses of X-ray (EDAX), Fourier transform infrared (FTIR) techniques and scanning electron microcopy (SEM), respectively. The anodic cerium oxide film is semi crystalline film. The heat treated anodic cerium oxide film at 550°C is the fluorite-structured cerium dioxide film, and the crystal structure of the cerium dioxide film becomes more complete than that of the anodic cerium oxide film. The cerium dioxide film is porous film. The water, ethylene glycol and CO₂ are adsorbed in the anodic cerium oxide film. The adsorbing water, ethylene glycol and CO₂ in the anodic cerium oxide film are removed at 550°C. The cerium dioxide film has strong absorption in the range of 1400~4000cm^-1.
