anion radicals on SnO2 is observed under physical adsorption of O2 molecules in an amount less than 1016 m–3. The thermal stability of sites for O

stabilization on SnO2 is analyzed. Molecular oxygen, forming O2, is shown to desorb with increasing temperature without participating in reoxidation of the oxide.
