- Аннотация: It was shown that the improvement of hydrogen sorption characteristics of the TiFe-based alloys can be achieved by:•Doping the base alloy with metallic additives, first of all, Mn and V. The maximum positive effect which includes preserving high hydrogen sorption capacity, merging two plateau segments on the pressure – composition isotherm, facilitating the activation, improvements of H absorption/desorption kinetics and poisoning tolerance, is achieved by introducing several transition metals which substitute both titanium (A=Zr, Hf) and iron (B=Mn, Ni, Cr, Co, V), at the stoichiometric ratio (Ti+A)/(Fe+B)=1.05–1.1. Addition of the minor amounts (up to 3 at.%) of the rare-earth deoxidizers also improves hydrogen sorption characteristics.•Controlled introducing of small (below 0.2 wt.%) additives of oxygen into alloy which results in the softening activation conditions and kinetic improvements.•Surface modification of the TiFe-based alloy by metal nanoparticles (Ni, Pd) catalyzing dissociative chemisorption of H2. •Development of composite materials containing nanoscale carbon taken alone or as a carrier of the catalytic metal nanoparticles mentioned above.
