IR-Spectroscopy of Radiation- Stimulated Processes of Adsorption, Radiolysis, and Hydrogenation on the Surface of Metals in Contact with Hydrocarbons

This chapter presents the results of IR spectroscopic studies of radiation-stimulated heterogeneous processes of adsorption, radiation-chemical decomposition (radiolysis) of hydrocarbons on the metal surface, and radiative hydrogenation of these surfaces under the action of gamma radiation. It deals with the spectrokinetic regularities, their features, and the mechanisms of radiation-stimulated adsorption and radiolysis of hydrocarbons in heterogeneous metal-hydrocarbon systems, in particular in heterogeneous Al (Be)-n-hexane systems, using reflection-absorption IR spectroscopy (IRRAS). The role of intermediate surface-active decomposition products in the process of heterogeneous radiolysis of hydrocarbons is discussed, as well as the influence of the surface relief of the metal in the dynamics of the change in the decomposition process on the rate of formation and the yield of final products of radiolysis.
