Abstract
The sol–gel technique is frequently used to prepare materials where surface properties are of major importance. These might be films, powders, high-surface area catalyst supports, and catalysts themselves. A surface-specific technique is therefore essential to determine quality and reproducibility of surfaces and to correlate properties to chemistry and structure. X-ray photoelectron spectroscopy has become a routine technique for many workers in this field, and this chapter serves to inform the sol–gel community about the benefits and pitfalls of this structural and analytical tool. Areas of application are described with some examples from the literature.
