作为氢替代清洁能源应用的关键环节，金属氢化物、复合氢化物等轻质固态储氢材料日益受到关注，因其储氢密度高而具有巨大的应用潜力。对材料成分进行改性以改善其不利的动力学、热力学和可逆性的深入研究，对表征方法提出了更高的要求，以深入研究提高吸放氢性能的机理。幸运的是，由于氢和氘的高散射截面，中子散射技术，包括中子衍射、非弹性中子散射、小角度中子散射和中子全散射技术，已成为表征金属氢化物和复合氢化物储氢机理的有力工具。本综述总结了最近利用中子散射技术开发先进固态储氢材料的重要成果。
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 materialsviataking advantage of neutron scattering techniques.
