| Abstract;Adsorption and desorption of carbon dioxide on sol-gel derived ceria films were investigated by thermal desorption and X-ray photoelectron spectroscopy. Transparent cubic ceria films were prepared by sol-gel processes using Ce(NH4)2(NO3)6 as a starting material and by firing the coatings at 550.DEG.C. in air. Carbon dioxide was adsorbed on the ceria film surface during the firing process and while the films were left standing in air after firing. The adsorbed species desorbed in two temperature ranges, a low temperature(LT) region between 100-600.DEG.C. and a high temperature(HT) region between 600-900.DEG.C.. Corresponding to the desorption of CO2 in HT region, the amount of the Ce3+ component in the ceria film increased, resulting in the release of oxygen from the film. (author abst.) |
