Dehydrogenation Tuning of Ammine Borohydrides using Double-Metal Cations



Yanhui Guo, Hui Wu, Wei Zhou, Xuebin Yu


The strategy of using double-cation to tune the temperature and purity of dehydrogenation of ammine borohydrides is reported. The first double-cation ammine borohydride, Li2Al(BH4)5¿6NH3, which forms a novel structure with ordered arrangement of Al(NH3)63+ ammine complexes and Li2(BH4)53- complex anions, is found to release over 10.0 wt.% hydrogen below 120 °C with favorable kinetics and high H-purity (>99%).
