Ternary Amides Containing Transition Metals for Hydrogen Storage: A Case Study with Alkali Metal Amidozincates

Abstract

The alkali metal amidozincates Li4[Zn(NH2)4](NH2)2 and K2[Zn(NH2)4] were, to the best of our knowledge, studied for the first time as hydrogen storage media. Compared with the LiNH2–2 LiH system, both Li4[Zn(NH2)4](NH2)2–12 LiH and K2[Zn(NH2)4]–8 LiH systems showed improved rehydrogenation performance, especially K2[Zn(NH2)4]–8 LiH, which can be fully hydrogenated within 30 s at approximately 230 °C. The absorption properties are stable upon cycling. This work shows that ternary amides containing transition metals have great potential as hydrogen storage materials.
