Abstract

In this chapter we present recent advances in the study of metal oxide surfaces and put them in relation to gas sensing properties. A reoccurring scheme is the dependence of chemical surface properties on the crystallographic orientation of the surface. This dependence will become more important in gas sensing applications as nanomaterials with controlled crystal shapes are being designed. In particular we focus on differences of the surface properties of the two polar surfaces of ZnO and the two most abundant bulk terminations of rutile TiO2, i.e. the (110) and (011) crystallographic orientations. On the example of these metal oxides, we describe the use of vacuum based surface science techniques, especially scanning tunneling microscopy and photoemission spectroscopy, to obtain structural, chemical, and electronic information.
