Abstract
As a crucial link in the application of hydrogen for an alternative clean energy, light-weight solid-state hydrogen storage materials, such as metal hydrides and complex hydrides, attract ever-growing attention, and they have a great application potential due to their high hydrogen storage densities. Intensive research performed on modifications of the composition of the materials to improve their unfavorable kinetics, the thermodynamics, and reversibility, put forward higher requirements to the characterization methods to study in-depth mechanisms of the improved hydrogen absorption and desorption performance. Fortunately, due to the high scattering cross-section of hydrogen and deuterium, neutron scattering techniques, including neutron diffraction, inelastic neutron scattering, small-angle neutron scattering, and neutron total scattering technology, have become powerful tools for characterizing hydrogen storage mechanism of metal hydrides and complex hydrides. This review summarizes the recent important outcome in developing advanced solid-state hydrogen storage materials via taking advantage of neutron scattering techniques.
