Abstract

A supercritical fluid process method has been developed for fabricating mesoporous zirconia thin films with enhanced thermal stability up to a temperature of 850 °C. Both the supercritical CO₂ and the precursor tetramethoxysilane play an important role in enhancing the thermal stability of these films. Powder X-ray diffraction, Atomic force microscope, spectroscopic ellipsometry and transmission electron microscope analyses show that the thin films fabricated by the supercritical fluid process method have a highly ordered mesoporous structure, a nanocrystalline inorganic framework and a high optical transparency. These zirconia thin films have potential applications as electrodes in solid oxide fuel cells where high thermal stability is essential.
