While single and multi-walled carbon nanotubes (CNTs) have been investigated as good potential candidates to achieve high hydrogen storage, reproducibility and mechanism of storage remain issues to be reckoned with. High purity level and the addition of certain metallic nanoparticles seem to improve the hydrogen storage capacity of CNTs. Gamma irradiation is presented here as an innovative method to generate and attach vanadium and nickel nanoparticles to CNTs. Hydrogen storage capacity of the resulting nanostructure will be analyzed. Further cleaning of CNTs by acid treatment is also studied here, which is aimed at reducing the presence of metallic impurities and create functional groups at the surface of the CNT. FTIR, SEM, STEM and XPS were used for morphological chemical and structural characterization of the nanostructures.
