Abstract :
In order to understand the influence of defect zones on desorption behavior of MgH 2 , Xe 120 keV ion irradiation of this material has been performed. DSC, SEM measurements, and SRIM calculations have been used to characterize induced modifications and its influence on the hydrogen desorption behavior of MgH 2 . We have demonstrated that the near-surface area of MgH 2 plays the crucial role in hydrogen desorption kinetics. DSC analysis provides clear picture of vacancies influence on H diffusion and desorption in MgH 2 , and points out that there is possibility to control the thermodynamic parameters by controlled ion bombardment.
