摘要: In situ Raman spectroscopy was used to monitor the dehydrogenation of ball-milled mixtures LiNH2–LiBH4–MgH2 nanoparticles. The as-milled powders were found contain a mixture Li4BN3H10 and Mg(NH2)2, with no evidence residual LiNH2 or LiBH4. It observed that both Mg(NH2)2 begins at 353 K. completely consumed by 415 K, while persisted continued release hydrogen up 453 At higher temperatures melts reacts MgH2 form Li2Mg(NH)2 gas. Cycling studies 423 K 8 MPa (80 bar) during rehydrogenation spectral modes reappear, indicating partial reversal transformation.
