The present investigation reports the effect of TiH₂ templated over graphene (TiH₂@Gr) on the hydrogen sorption characteristics of MgH₂/Mg. The as synthesized TiH₂@Gr leads to significant effect on sorption in MgH₂ by the following effects: the first is dehydrogenation of MgH₂–TiH₂@Gr, which leads to the conversion of some part of TiH₂ into TiH_1.924. TiH₂ together with TiH_1.924 works as a better catalyst than TiH₂ alone. The second is ball-milling of TiH₂@Gr, which produces defective graphene, which also works as co-catalyst. The third is anchoring of TiH₂ on graphene, which does not allow the catalyst to agglomerate. The catalytic effect of TiH₂@Gr on MgH₂ is found to be better than Ti@Gr and TiO₂@Gr. The onset desorption temperature for MgH₂–TiH₂@Gr is ~204 °C, which is 31 °C and 36 °C lower than MgH₂–Ti@Gr, MgH₂–TiO₂@Gr respectively. The better catalytic behavior of TiH₂@Gr also persists during de/re-hydrogenation kinetics and cycling study of MgH₂. The feasible mechanism for superior catalytic for TiH₂@Gr on MgH₂ has been put forward.

本研究报告了在石墨烯上模板化的TiH ₂（TiH ₂ @Gr）对MgH ₂ / Mg氢吸附特性的影响。合成的TiH ₂ @Gr通过以下作用对MgH ₂的吸附产生显着影响：首先是MgH ₂ -TiH ₂ @Gr的脱氢，这导致TiH _2的一部分转化为TiH _1.924。TIH ₂连同TIH _1.924作品比TIH更好的催化剂₂孤单。第二种是TiH ₂的球磨@Gr会产生有缺陷的石墨烯，该石墨烯也可以用作助催化剂。第三是将TiH ₂锚固在石墨烯上，这不允许催化剂团聚。发现TiH ₂ @Gr对MgH ₂的催化作用优于Ti @ Gr和TiO ₂ @Gr。MgH ₂ -TiH ₂ @Gr的起始解吸温度为〜204 °C，分别比MgH ₂ -Ti @ Gr，MgH ₂ -TiO ₂ @Gr低31°C和36°C 。TiH ₂ @Gr的更好的催化行为在MgH ₂的脱氢/再氢化动力学和循环研究中也持续存在。TiH高级催化的可行机理₂ @Gr上的MgH ₂已经被提出。
