Abstract

As a promising hydrogen storage composite, the ɑ-AlH3/LiCl nano-composite was prepared by mechanochemical synthesis method. However, so far there is no investigation on the dehydriding property of this composite. In present work, the hydrogen desorption property of this composite is investigated systematically. When heating temperature goes from 80 to 140 °C, the isothermal desorption measurements show that 9.93 wt% of hydrogen is released from the composite and the kinetic of the dehydrogenation improved with the temperature raised. Moreover, thermal analysis by differential scanning calorimeter (DSC) is used to research the de-hydriding process of the ɑ-AlH3/LiCl nano-composite, from which the composite composes one step with the direct decomposition of the α phase. With the LiH introduced into the AlH3/LiCl nano-composite, the dehydrogenation measurements reveal that the de-hydriding kinetics of this system was also improved. According to the DSC results, it is found that the LiH addition can reduce the activate energy of the de-hydriding reaction.
