Application of adsorbed molecules as probes for EXAFS study of surface

Abstract

This work is devoted to some aspects and problems of application of adsorbed molecules as probe for EXAFS study of surface. Two systems were investigated: (1) Ni/C - nickel catalysts of obtaining of carbon by methane decomposition, (2) α-Fe2O3 - α-iron oxides were prepared in two ways, namely, by oxalate and goethite decomposition. The perspective of the used approach for surface testing of catalysts and for study of reaction courses is shown. However, it is clear from our work that it is necessary to have a wider set of probes, both selectively and non-selectively adsorbed on the surface.
