The hydrogen storage mechanism of materials is usually divided into chemisorption and physisorption according to the way the material interacts with hydrogen. Chemisorption refers to the breaking of hydrogen molecules into hydrogen atoms, which are then bonded to materials through chemical bonds. Physisorption refers to the adsorption of hydrogen molecules on the surface of materials with high specific surface areas through van der Waals forces. With the development of materials science and characterization techniques, some new hydrogen storage materials are emerging, which exhibit relatively complex interactions with hydrogen. This review will focus on non-classical hydrogen storage materials and mechanisms beyond physisorption and chemisorption, including Kubas interactions, nanopump effects, non-dissociative chemisorption, and weak-confined insertion of hydrides. This review will give researchers a clear view of the diversity of hydrogen storage materials and the complexity of hydrogen storage mechanisms, which may help enrich future hydrogen storage materials.

化学吸附和物理吸附以外的非经典储氢机制

材料的储氢机理通常根据材料与氢相互作用的方式分为化学吸附和物理吸附。化学吸附是指氢分子断裂成氢原子，然后通过化学键与材料结合。物理吸附是指氢分子通过范德华力吸附在高比表面积材料的表面。随着材料科学和表征技术的发展，一些新型储氢材料不断涌现，它们与氢之间的相互作用相对复杂。本综述将重点关注非经典储氢材料和物理吸附和化学吸附以外的机制，包括 Kubas 相互作用、纳米泵效应、非解离化学吸附、和氢化物的弱限制插入。这篇综述将使研究人员清楚地了解储氢材料的多样性和储氢机制的复杂性，这可能有助于丰富未来的储氢材料。
