英文摘要	The application of ammonium borane (AB) as a hydrogen storage material is limited by the sluggish kinetics of H, release. Two catalysts based on metal organic frameworks (MOFs) have been prepared either by applying MOF as precursors or by the in situ reduction method. In the release of H-2 from AB, the high H-2 content of the whole system, the remarkably lower reaction onset temperature, the significantly increased 117 release rates at <= 90 degrees C, and the decreased reaction exothermicity have all been achieved with only 1.0 mol% MOF-based catalyst. Moreover, the clear catalytic diversity of three catalysts has been observed and discussed. The in situ synthesized Ni-0 sites and the MOF supports in the catalysts were proven to show significant and different effects to promote the catalytic activities. With MOF-based catalysts, both the enhanced kinetics and the high H-2 capacity of the AB system present great advantages for future use.
