AbstractZr(BH4)(4)center dot 8NH(3) is considered to be a promising solid-state hydrogen-storage material, due to its high hydrogen density and low dehydrogenation temperature. However, the release of ammonia hinders its practical applications. To further reduce the dehydrogenation temperature and suppress ammonia release, here we investigated its hydrolysis process to evaluate its hydrogen generation performance. The results showed that the hydrolysis of Zr(BH4)(4)center dot 8NH(3) in water can generate about 1067 mL g(-1) pure hydrogen in 240 min at 298 K without the release of diborane or ammonia impurity gases. With heatassistance, the hydrogen generation rate can be significantly enhanced, and its activation energy was calculated to be 29.38 kJ mol(-1). The hydrolysis mechanism was clarified. The results demonstrate that Zr(BH4)(4)center dot 8NH(3) may work as one promising hydrogen generation material.
