Abstract

In this study, we report the hydrogen storage in aluminum hydride coated single-walled carbon nanotube. All the H2 adsorption is molecular with HH bond length of 0.756 Å. The hydrogen storage capacities with half and full coverages are 6.01 (8.3) wt% and 7.2 (10.3) wt%, respectively, without (with) H3 of AlH3. At high coverage of AlH3 (C10AlH3) interesting clustering/ dimerization of AlH3 is observed. These systems are quite stable and the H2 can be extracted from the system without disturbing the CAl bonding or detaching the AlH 3 from the carbon nanotube. This present study on a full molecular adsorption of hydrogen via light metal-hydride AlH3 is new and it leads to a practically viable hydrogen storage process.
