Abstract To explain the catalytic properties inherent to a number of coatings
formed by the method of plasma-electrolytic oxidation (PEO), a series of Ni- and/or
Cu-containing coatings on aluminum were investigated by X-ray photoelectron
spectroscopy (XPS). It was determined that the main components of the surface
layers of these coatings are a variety of oxide structures of the base and electrolyte
elements – oxides of aluminum, nickel, copper, and more complicated composite
structures. In this chapter, our experimental results are introduced.

oxidation · Metal oxide coating
11.1 Introduction
Design and investigation of various novel functional materials have been the main
objectives in modern material science. It was recently found that coatings formed
by the method of plasma-electrolytic oxidation (PEO) and containing 3d element(s)
have a pronounced catalytic activity in the oxidation of CO to CO 2 [1–7]. Since the
surface plays a decisive role in heterogeneous catalysis, our research has emphasized
to investigate the composition and structure of the surface layers of the metal oxide
