| Abstract: | Chemisorption of SO2 and O2 on the In2O3 surface containing a zinc additive (0.4–2.7 at.%) was studied in a temperature range of 22–200 °C. At least three forms of sorbed SO2 exist on the modified In2O3 surface. The temperature affects the contribution of single forms of SO2 sorption and, hence, the change in the electric conductivity. The preliminary sorption of O2 favors the formation of a donor form of chemisorbed SO2. Published in Russian in Izvestiya Akademii Nauk. Seriya Khimicheskaya, No. 10, pp. 2228–2232, October, 2005. |
