A nanosheet-like lithium borohydride hydrate (LiBH·HO) measuring 20-30 nm in thickness is successfully synthesized for the first time by a facile, scalable freeze-drying strategy. The prepared LiBH·HO nanosheets start releasing hydrogen below 50 °C and release an amount up to approximately 10 wt % at 70 °C because of the strong affinity of H in the HO ligand and H in the BH group. The reported dehydrogenation properties here are superior to those of all known complex hydrides, indicating applicability as an advanced chemical hydrogen storage medium.
首次通过一种简便、可扩展的冷冻干燥策略成功合成了厚度为20 - 30纳米的纳米片状硼氢化锂水合物（LiBH₄·H₂O）。所制备的LiBH₄·H₂O纳米片在低于50℃时开始释放氢气，并且由于H₂O配体中的H与BH₄基团中的H具有很强的亲和力，在70℃时释放量高达约10 wt%。此处报道的脱氢性能优于所有已知的复合氢化物，表明其作为先进化学储氢介质的适用性。
