Abstract
This paper reports the results of work function and EPR studies of yttria-stabilized zirconia (10Y-ZrO2). The experimental data are considered in terms of the formation of oxygen chemisorbed species and subsequent oxygen incorporation as well as related charge transfer. It is concluded that oxygen chemisorption on 10Y-ZrO2 at room temperature in its initial stage results in the formation of O −2 species. These species are then transformed into O 2−2 , O− species and, finally, are slowly incorporated into the oxide lattice. These processes take place without presence of Pt or any other electrode material.
