Paper Abstract

Thin films of CeO2-TiO2-ZrO2 with 23 percent mol of Ce, 45 percent mol of Ti and 32 percent mol of Zr have been prepared by the sol-gel method. The precursor sol was synthesized from a mixture of Ce(NH4)2 (NO3)6, Ti(OPi)4 and Zr(OPi)4 solubilized in isopropanol and then sonicated. Xerogels were characterized by thermal analysis and x-ray diffraction. The films were deposited by dip-coating technique on ITO-Asahi glass and tread at 80 degrees C during 15 min and 450 degrees C during 15 min in oxygen atmosphere. Through the addition of lithium salt to the precursor solution films with different electrochemical performance are obtained. Their possible use as ion storage in electro chromic devices was analyzed by spectroelectrochemical measurements using cyclic voltammetry and chronoamperometry coupled to spectrometric measurement.
