Research Progresson Effects of Different Catalystson Hydrogen Absorption and Desorption Kinetics of Magnesium Base Alloys

文章主要综述了不同催化剂对镁基合金吸放氢速率的影响,通过研究发现,金属复合催化剂催化效率最佳,比如MoNi合金纳米粒子表现出色的催化效果,甚至比大多数先进的Ti基催化剂效果更好,并且在简短时间内释放出高达6.7%的氢。复合材料催化剂的效果也相当显著,不仅可以缩短脱氢时间,同时降低反应活化能。

This article mainly reviews the effects of different catalysts on the hydrogen absorption and desorption rate of magnesium based alloys,By summarizing,it is found that the metal composite catalyst has the best catalytic efficiency.For example,MoNi alloy nanoparticles show excellent catalytic effect,even better than most advanced Ti-based catalysts,and releasing up to 6.7%of hydrogen in a short time.The effect of composite material catalysts is also quite significant,which can not only shorten the dehydrogenation time,but also reduce the activation energy of the reaction.
