Both CaH₂ and MgH₂ are good candidate for the development of hydrogen storage materials because of their high hydrogen storage capacity. However, both the hydrides are quite stable thermodynamically and required high temperature for hydrogen sorption process. The MgH₂–CaH₂ composite could show the favourable hydrogen sorption reaction because of Ca–Mg intermetallic formation. The idea motivated to perform the experiments starting with these metal hydrides. It has been found that the hydrogen sorption reaction kinetics improved substantially. The dihydrogen product has shown a few intermetallic of magnesium and calcium. The hydrogen sorption temperature and pressure of the alloy was remarkably improved by the doping with ZrCl₄ as a catalyst. The activation energy and the thermodynamic parameters of un-catalyzed and catalyzed alloy were studied. Present studied indicated that the CaH₂–MgH₂–ZrCl₄ could be a potential candidate for the mobile hydrogen storage system.

CaH ₂和MgH ₂都是开发储氢材料的良好候选者，因为它们具有高储氢能力。然而，这两种氢化物在热力学上都非常稳定，并且吸氢过程需要高温。由于形成了 Ca-Mg 金属间化合物，MgH ₂ -CaH ₂复合材料可以显示出有利的氢吸附反应。这个想法促使从这些金属氢化物开始进行实验。已经发现氢吸附反应动力学显着改善。二氢产物显示出一些镁和钙的金属间化合物。ZrCl的掺杂显着提高了合金的吸氢温度和吸氢压力₄作为催化剂。研究了未催化和催化合金的活化能和热力学参数。本研究了表明氢化钙₂ -MgH ₂ -ZrCl ₄可以是用于该移动氢存储系统的潜在候选者。
