Abstract

This study reports an all-round enhancement in the hydrogenation properties of Pd–Pr layers due to ion tracks formed on irradiation with 120 MeV Ag+10 ions. About 17.8% increase in the hydrogen stoichiometry value during loading, near maximal removal (about 31%) during deloading, and increase in the active layer thickness are observed on ion irradiation. Nonequilibrium structural change during ion-induced shock wave generation results in the formation of nanotracks throughout the film thickness, which provide two-way transport routes for H diffusion. This study thus provides an effective methodology of improving the hydrogenation properties of materials
