Effect of Catalysts on the Reaction Kinetics of Metal-N-H Hydrogen Storage System:A Review

阐述了金属氮氢系贮氢材料中Li-N-H体系和Li-Mg-N-H体系贮氢材料反应机制和催化动力学的研究进展,分析讨论反应机制和反应动力学中的控制步骤。基于此,进一步讨论不同催化剂对该体系贮氢材料吸放氢催化反应过程的影响,并深入探讨不同催化剂与催化动力学的相关性,为该体系贮氢材料的反应动力学催化研究提供参考。

The development of metal-N-H hydrogen storage system, Li-N-H and Li-Mg-N-H series, is elucidated, especially for their progress in the reaction mechanism and effect of catalysts on reaction kinetics. Subsequently, the most possible reaction mechanism and the reaction limited steps in this mechanism are explored and summed up. Furthermore, we probe into the effects of different catalysts on the reaction steps in these materials, and then we deeply clear up the catalytic interaction between the additives and reaction kinetics. Therefore, this would be a recommendable reference for the research on reaction kinetics in this hydrogen storage system .
