“…reported differences in the surface reactivity depending on the oxidation state of the surface [22]. However, the (1 1 0) surface is less well-defined compared to the (1 0 1) surface because the (1 1 0) surface forms complex surface reconstructions upon surface reduction [4].…”

“…In order to prepare a 1×1 surface with a high oxygen concentration ion sputtered SnO 2 (110) surfaces have to be annealed in an oxidizing gas (O 2 [31] or N 2 O [32,33]) or exposed to an oxygen plasma [34] at elevated temperature. The surface structure that is prepared by exposing the surface to 10 -3 mbar O 2 at elevated temperature [29] is shown in figure 4.…”

Abstract:This review is an attempt to give an overview on how surface science studies can contribute to a fundamental understanding of metal oxide gas sensors. In here tin dioxide is used as a model system for metal oxide gas sensor materials and we review surface science studies of single crystal SnO2. The composition, structure, electronic and chemical properties of the (110) and (101) surfaces is described. The influence of compositional changes as a function of the oxygen chemical potential on the electronic surface structure and the chemical properties is emphasized on the example of the (101) surface. The surface chemical properties are discussed on the example of water adsorption. It is shown the chemical and gas sensing properties depend strongly on the surface composition.

“…N 2 O is also used in oxidation treatment of SnO 2 ͑110͒ surface by Gercher et al 31 Several studies 2,17,18 have reported that H 2 O oxidized Ti 3ϩ to Ti 4ϩ to heal defects and produced H 2 . In fact, O 2 is often used as oxidizing agents by most groups to make defect-free TiO 2 surfaces.…”
