摘　　要：MgH_(2)(氢化镁)因其资源丰富、成本低廉、储氢容量高和无污染等特点,被认为是最具应用前景的固态储氢材料之一,但其存在动力学和热力学性能较差的问题。过渡金属单质及其化合物催化改性MgH_(2)能有效降低吸放氢的温度和活化能,提升循环稳定性。综述了过渡金属及其化合物在镁基储氢材料的催化改性研究进展,归纳了这些材料的合成方法以及其在MgH_(2)中的改性方法和机制,结果表明,过渡金属基催化剂的改性效果主要受催化剂元素种类、配比、含量以及载体种类和制备工艺等因素的影响。最后,展望了过渡金属基催化剂未来研究方向,旨在为高性能镁基储氢材料的研发提供借鉴。Magnesium hydride(MgH_(2))is considered as one of the most promising solid-state hydrogen storage materials for application due to their abundant resources,low cost,high hydrogen storage capacity,and non-pollution.However,it also suffers from the drawbacks of the poor kinetic and thermodynamic.Transition metals and their compounds are applied to catalyze MgH_(2) and effectively lower the dehydrogenation and rehydrogenation temperature,reduce the activation energy,and improve the cycling property.The paper reviews the research progress of transition metals and their compounds in catalytic modification of MgH_(2),and summarizes the application synthesis methods,modification ways,and modification mechanisms.The results indicate that the modification effect is mainly affected by the type,ratio,and content of catalyst elements,as well as carrier type and preparation technology.Finally,it also outlooks the future research direction of transition metal-based catalysts in order to provide the reference for the research and development of high performance magnesium-based hydrogen storage materials.
