Zr(BH4)(4).8NH(3) is considered to be a promising solid state hydrogen-storage material, due to its high hydrogen capacity and low dehydrogenation temperature. However, the possible applications of Zr(BH4)(4).8NH(3) have been greatly hampered by the complicated and less applicable synthesis process, which must be operated at relatively low temperature (<20 degrees C). Herein, we reported a simple and facile "heating-(ball milling) BM vial" method via physical vapour deposition to tackle this issue. By this technique, Zr(BH4)(4).8NH(3) was successfully synthesized. Furthermore, composite formation by adding 10 wt% NaBH4 to the as-prepared Zr(BH4)4.8NH3 was found to be able to lower down the dehydrogenation peak of Zr(BH4)(4.8)NH3 from 130 to 75 degrees C and more excitingly, the possible emission of B2H6 and NH3 from dehydrogenation of only Zr(BH4)(4).8NH(3) was completely suppressed after addition of NaBH4. This research presents a new hydrogen-storage system based on Zr(BH4)(4).8NH(3)+NaBH4 composite and it also implies a new development methodology of future hydrogen storage materials.
