Changes in Storage Properties of Hydrides Induced by Ion Irradiation
Keywords:hydrogen storage, MgH2, ion irradiation, TPD, non- isothermal kinetics
The influence of structural changes caused by irradiation with different ions, their energies and fluences on sorption properties has been investigated. Results suggest that there are several mechanisms of desorption depending on defect concentration, their interaction and ordering. It has been also demonstrated that the changes in near-surface area play the crucial role in hydrogen desorption kinetics. It is confirmed that there is possibility to control the thermodynamic parameters of these systems by controlling vacancies depth profile and concentration.
