报道了一种新型复合储氢体系LiBH 4/[C（NH 2）3]+[BH 4]−（GBH）复合物。将LiBH_4和氯化胍进行短时球磨，合成了一系列新的LiBH_4/GBH配合物。发现两种潜在的储氢材料表现出相互的脱氢改善，释放>10.0 wt.%在低于250 °C下从LiBH 4/GBH获得相当纯的H2。进一步的研究表明，平衡质子氢和质子氢以及LiBH_4和GBH之间的络合作用是提高该体系脱氢性能的两个重要因素，这可能为开发具有良好脱氢性能的金属硼氢化物/B-N-H体系提供一种替代策略。
A novel combined hydrogen storage system LiBH4/[C(NH2)3]+[BH4]− (GBH) complexes were reported. By a short time ball milling of LiBH4 and guanidinium chloride, a series of new LiBH4/GBH complexes were produced. It was found that the two potential hydrogen storage materials exhibited a mutual dehydrogenation improvement, releasing >10.0 wt.% of fairly pure H2 from LiBH4/GBH below 250 °C. Further investigations revealed that balancing the protic and hydridic hydrogens, and the complexation between LiBH4 and GBH, are two important roles in the improvement of the dehydrogenation of this system, which may serve as an alternative strategy for developing a new metal borohydride/B–N–H system with favourable dehydrogenation.
