Hydrogen storage is of great importance today as a source of clean and renewable energy. Adsorption on surface adsorbents is one of the effective methods in this storage. Suitable adsorbents suggested include metal hydrides and carbonaceous materials. Recently, nanostructured carbon compounds such as graphite, carbon nanotubes, and graphene have been used to store hydrogen due to their high surface area and high porosity, which have a higher storage capacity and a higher rate of hydrogenation and dehydrogenation. The bond between the carbon atoms here is covalent and very strong. Therefore, carbon materials are very strong. On the other hand, in order to increase the amount of adsorption energy and increase hydrogen storage, intermetallic compounds with other intermediate metals and their alloys can be created using traort metals such as titanium, nickel and vanadium. Transfer metals such as titanium have received more attention than other transfer metals due to the formation of stronger and stronger bonds with hydrogen and titanium hydride. In this research, Ni-Al intermetallic compound is formed by mechanical alloying method and then titanium powder is added during each step and the amount of aluminum powder is reduced and then sampled to finally reach Ni-Ti intermetallic compound. Finally, in order to further increase hydrogen adsorption, samples are formed by nanocomposite mechanical alloying with carbon nanotube powder and then microstructure changes, hydrogen adsorption and desorption behavior and specific surface area of ??the compounds using X-ray diffraction, electron microscopy, surface analysis and Are specially examined. key words Hydrogen storage, metal hydride, carbon nanotubes, hydrogen adsorption and desorption
