An overview of RE-Mg-based alloys for hydrogen storage: Structure, properties, progresses and perspectives

• Hydrogen storage properties of different RE-Mg system alloys were evaluated. • Evaluation of electrochemical properties of superlattice-type RE-Mg-based alloy. • Elucidation of the catalytic mechanism of catalysts for RE-Mg alloy system. • A feasible idea for rational design of RE-Mg-based alloys was provided. Rare earth (RE) elements have been successfully utilized in solid-state hydrogen storage as hydrogen-absorbing elements with excellent hydrogen storage properties in terms of safety and efficiency. RE-Mg-based hydrogen storage materials with high magnesium content are considered to be one of the most promising hydrogen storage materials for application due to their high mass/volume hydrogen storage…
