LaNi〓 can be easily activated at room temperature and activated LaNi〓 possesses catalysing effect for the dissociation of H〓, which greatly reduces the energy barrier for dissociation of H〓. Hydrogen passed through LaNi〓 particles, then diffused into the crystal lattices of V、Nb and TiFe alloy and formed hydrogenate.

LaNi〓粒子在室温下很容易活化，活化后的LaNi〓具有了氢分子分解为氢原子的催化作用，降低了氢分子分解为氢原子所必须克服的势垒，氢通过LaNi〓粒子而进入V、Nb、TiFe合金晶格中，形成金属氢化物。

For the first time we synthesized nanoscale metal hydrides of lanthanum, neodymium, samarium, dysprosium, and ytterbium with high efficiency under mild condition by complexometric catalysis instead of traditional preparation at high temperature and high pressure. It is for the first time that we synthesized lanthanide organic compounds with catalysts or initiating agents at atmosphere and ambient temperature,and some of them are new compounds. Nanometric lanthanide metal powders are prepared by thermal decomposition of the compounds in vacuum. Differently from the traditional method, size of the products prepared by our method is less than 40nm, and the activity of the reaction is very high. They are pyrophoric at atmosphere. They can make some reactions without activity or low activity show extremely high activity .We investigated influent regulations of methods, conditions to scale and special surface.
