Реферат: The influence of surface composition on hydrogen activation in the process of liquid-phase hydrogenation of organic compounds was determined by the investigation of intermetallic hydrides LaNi5-xCuxHn(x = 1–4) and La1-xCexNi5Hn(x = 0.15–0.35). The complex of physicochemical methods showed that the formation dynamics and the nature of the active surface layer are determined by both the preliminary processing conditions and the reaction medium impact. It is shown that by varying the reaction medium composition it is possible to give a useful rise in the preferential segregation of one of the alloy components and to create active centers with definite composition on the surface. The investigation of the dependence of hydride catalytic activity on intermetallic nature, hydride forming pressure, sorption capacity and hydride surface composition allows us to draw the conclusion that surface center composition has a decisive influence on both hydrogen sorption-desorption kinetics and organic compound hydrogenation.
