Abstract: Carbon nanotubes(CNTs) decorated with palladium were synthesized and applied to hydrogen storage of gas phase. The results show that the amount of hydrogen storage of the decorated CNTs is up to 3.9%(mass fraction), of which, almost 85% H2 can be desorbed at ambient temperature and pressure, while the non-decorated CNTs has a poor performance of hydrogen storage(only about 0.5%H2, mass fraction). These indicate that it is feasible to enhance the performance of hydrogen storage of CNTs by further decoration with hydrogen-storing metals or alloys.
Key words: carbon nanotubes; hydrogen-storing metals; hydrogen-storing alloys; palladium; hydrogen storage
