摘　　要：在固态储氢材料中,Li-Mg-N-H体系储氢材料因其热力学性能好、可逆性好、理论储氢容量高等特点被认为是最有前景的储氢材料。然而,由于Li-Mg-N-H体系的动力学性能较差,导致其在200℃以上才能进行快速吸放氢反应。因此,文章从成分调控、纳米化和掺杂催化剂3个方面论述了Li-Mg-N-H体系热力学和动力学调控的研究现状,并指出未来研究方向。Among the solid-state hydrogen storage materials,Li-Mg-N-H system hydrogen storage materials are considered to be the most promising hydrogen storage materials due to their good thermodynamic properties,good reversibility and high theoretical hydrogen storage capacity.However,due to the poor kinetic properties of the Li-Mg-N-H system,the rapid hydrogen absorption and desorption reaction can only be carried out above 200 ℃.Therefore,the current research status of thermodynamic and kinetic regulation of hydrogen storage materials in Li-Mg-N-H system is reviewed in detail from three aspects of composition regulation,nanization and doping catalyst,and the future research direction is pointed out.
