实现氢能有效利用的关键技术是开发安全、经济、高效的氢能储运体系。在目前所有的储氢技术中,固态材料化学储氢因其储氢密度大、可循环使用、安全方便储运等优势成为人们关注的焦点;配位氢化物储氢材料是现有储氢材料中体积和质量储氢密度最高的储氢材料。其中,具有高储氢密度、储氢性能优良的轻金属配位氢化物储氢材料是配位氢化物储氢领域研究的重点,目前已经取得了大量成果。本文论述了主要轻金属配位氢化物储氢体系的研究进展,包括硼氢化物储氢体系、铝氢化物储氢体系、氨基化物储氢体系等,阐述和总结了其热解反应机理、动力学性能、晶体结构、最新研究现状,最后对该领域的研究方向进行了总结和展望,指出二元或多元复合储氢体系、高效纳米粒子催化剂和储氢反应环境的综合协同效应将会成为储氢领域未来的研究趋势和重要研究方向。
The key technology for hydrogen energy effectively is to develop safe, economical and efficient hydrogen storage system. Among all the hydrogen storage technologies at present, solid-state hydrogen storage material has got a lot of attentions because of its outstanding advantages including high density, excellent cycle property, safe and convenient storage mode. Complex hydride material has the highest hydrogen storage density ; and light metal complex hydride hydrogen storage systems （LMCHHSS） which have high hydrogen storage density and excellent hydrogen storage property are the research emphasis with good achievements. The decomposition mechanisms, thermodynamic and kinetic properties, cycling performances, crystal structures, research status of LMCHHSS, including borohydride system, alanate system and amide system, are discussed in the paper. At last, some promising research directions to reduce thermodynamic stability, improve kinetic property and cycling hydrogen storage property, such as binary or multicomponent composite system, efficient catalyst nanoparticle, superior reaction environment, or the comprehensive synergistic effect of the above, are suggested for the developing trends of the domain in the future.
