Application of layered InSe and GaSe crystals and powders for solid state hydrogen storage

Abstract

Processes of hydrogen electrochemical intercalation into layered InSe and GaSe crystals and its deintercalation were investigated. It was ascertained that for concentrations x < 2 hydrogen mainly enters in interlayer space and forms H 2 molecules, where is the amount of introduced atoms per one formula unit of the crystal bulk. For 2 < x <4 atomic hydrogen being built into interstices due to quantum-size effects for the gap and H2 molecules. © 2007 Springer.
