| 英文摘要 | In this work, the hydrogen absorption and desorption properties of the system K-2[Zn(NH2)(4)]-8LiH are investigated in detail via in situ synchrotron radiation powder X-ray diffraction (SR-PXD), Fourier transform infrared spectroscopy (FT-IR), and volumetric methods. Upon milling, K-2[Zn(NH2)(4)] and 8LiH react to form 4LiNH(2)-4LiH-K2ZnH4, and then 4LiNH(2)-4LiH-K2ZnH4 releases H-2 in multiple steps. The final products of the desorption reaction are KH, LiZn13, and Li2(N)H. During rehydrogenation, KH reacts with LiZn13 under 50 bar of hydrogen producing K3ZnH5. This phase appears to enhance the hydrogenation process which after its formation at ca. 220 degrees C takes place in only 30 s. The system 4LiNH(2)-4LiH-IC2ZnH4 is shown to be reversible under the applied conditions of vacuum at 400 degrees C for desorption and 50 bar of H-2 at 300 degrees C for absorption. |
