Nanostructuring - a possible way to enhance the hydrogen sorption properties of materials

Effect of nano-structuring on hydrogen sorption properties of materials

Storage of large quantities of hydrogen at safe pressures is a key factor in establishing a hydrogen-based economy [1]. Of the three ways of storing hydrogen, viz. by compressed gas, in liquid form, or as hydride, the latter is rather promising both for its relevant storage capacity and safety [2]. There are several materials which show reversible hydrogen absorption desorption properties. However, to be suitable for the on-board hydrogen storage for vehicular applications, the storage material should have the following properties: (a) high storage capacity; (b) moderate absorption/desorption temperatures; (c) fast hydrogenation/dehydrogenation kinetics; (d) high resistance to degradation a…
