IRRAS study of radiations stimulated adsorption and radiolysis of water on the surface of aluminium

Full Text: Infrared reflection absorption spectroscopy (IRRAS) was apllied to study the radiation stimulated adsorption and radiation heteregenous conversion of water on the surface of aluminium. It was established that the adsorption centers of H2O on the surface of aluminium under action of γ quanta arise on the basis of molecular and dissiciative mechanism at the room temperature. It was shown that the radiolysis of water in heterosystem AL-ads.H2O leads to the formation of surface hydroxides, hydrides and molecular hydrogen, as well as a formation oxide layers on the surface Al. A possible scheme of radiation-heteregenous conversion H2O was proposed in the system of Al-adsH2O
