Low-Energy Ion Scattering Investigations of Catalysts II

Part of the NATO ASI Series book series (NSSB, volume 265)

Abstract

Real catalysts are multi-component systems. There is at least one major component finely dispersed on a high surface area support and frequently there are additional components added which act as promotor substances, conferring advantages to the catalyst with respect to activity, selectivity, or stability. Hence, catalysts are adsorption systems that generally are very complex in composition and structure. Since ion scattering spectroscopy (ISS) is specifically sensitive to the outermost atomic layer of a surface /1,2/ and since the catalytic properties may be mainly determined by the outermost chemical species, ISS is well suited to gain useful information about catalytic systems /3/.
