Surface engineering approaches were adopted in the preparation of advanced hydrogen sorption materials, based on 'low-temperature', AB5-type intermetallides. The investigated included micro-encapsulation with palladium and mixed-metal mantles using electroless plating. influence surface morphology kinetics charging investigated. It was found that palladium-nickel (Pd-Ni) co-deposition by plating significantly improved intermetallides at low pressure temperature, after long-term pre-exposure to air. improvement credited a synergistic effect between nickel atoms catalytic mantle formation an 'interfacial bridge' for diffusion deposited layer. developed surface-modified materials may find application highly selective extraction, purification, storage from impure feeds.
