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