The processes of hydrogen deintercalation in intercalated nanophases based on layered 2H-WS2 and 2H-MoS2 nanostructures are investigated by mass-spectrometry method. As revealed, at deintercalation of intercalated HxWS2 (0??х???1.55), HxMoS2 (0??х???0.45) nanophases, hydrogen is released in a molecular state (H2) in temperature intervals of 500–1420 K, 700–1420 K, respectively. As shown, the disordering of layered intercalated HхWS2 and HхМоS2 nanostructures essentially influences on characteristics of hydrogen deintercalation process. Hydrogen intercalation–deintercalation processes in intercalated nanophases based on layered 2H-WS2 and 2H-MoS2 nanostructures are thermodynamically convertible.
