利用已提出的还原氢态理论、氢化物理论以及电化学理论分别以次磷酸盐、硼氢化物以及次磷酸盐与硼氢化物作为复合还原剂条件下，对镀层的反应机制进行了系统的讨论。

The additional activity of the mechanical mixture can be ascribed to the acid sites on dealuminated Y zeolite, where the activated hydrogen spilt over from the neighboring Pt sites could hydrogenate the adsorbed benzene with the formation of cyclohexane and methylcycloheptane.

发现虽然Y沸石本身没有加氢活性，但它的加入可以显著提高Pt/Al2O3的活性，因为在Pt中心上得到活化的氢可以快速溢流到邻近的沸石颗粒表面的酸中心上，并和吸附在其上的苯发生加氢反应生成环己烷和甲基环戊烷。

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。
