由于仍然没有安全、高密度的方法来储存氢气，使用氢气作为能源载体的希望受到严重打击。我们研究了使用金属氨络合物作为固体形式储氢的可能性。以Mg(NH3)(6)Cl-2为例，我们表明它可以以氨的形式储存9.1%重量的氢。储存是完全可逆的，通过将其与氨分解催化剂相结合，可以在低于 620 K 的温度下输送氢气。
The hopes of using hydrogen as an energy carrier are severely dampened by the fact that there is still no safe, high-density method available for storing hydrogen. We investigate the possibility of using metal ammine complexes as a solid form of hydrogen storage. Using Mg(NH3)(6)Cl-2 as the example, we show that it can store 9.1% hydrogen by weight in the form of ammonia. The storage is completely reversible, and by combining it with an ammonia decomposition catalyst, hydrogen can be delivered at temperatures below 620 K.
