Methods of theoretical calculations and of experimental researches of the system atomic hydrogen – metal

Abstract All the main directions of energy development suggest or already implement the use of hydrogen. In addition, the interaction of low-energy hydrogen atoms with metals is also of considerable interest, both from the point of view of fundamental research and in connection with the operation of large tokamaks and thermonuclear reactors. The paper presents a literature review of the features of the interaction of hydrogen with metals. It is shown that metal-hydrogen reactions, which lead to the formation of metal hydrides, are considered as a special type of such interaction. Modern methods of experimental study of heterogeneous reactions, topochemistry of metal - hydrogen reactions, dependences of the rate of interaction on pressure and temperature are considered, models of surface processes occurring during the interaction of hydrogen with a metal are discussed. A kinetic method for studying the mechanism of interaction of atomic hydrogen with hydride-forming metals is proposed.
