Hydrogen Release From Ammonia Borane
Development of a safe and efficient storage medium for hydrogen is integral to its use as an alternative energy source. The overall goal of the studies described in this dissertation was to investigate the use of a chemical hydride, ammonia borane (AB (19.6 wt% H2)), as a potentially efficient material for hydrogen storage. The specific goals of this study were both to develop new efficient met...
متن کاملPromotion of hydrogen release from ammonia borane with magnesium nitride.
Hydrogen release from ammonia borane (NH(3)BH(3), AB) can be greatly promoted by mechanical milling with magnesium nitride (Mg(3)N(2)). For example, a post-milled 6AB/Mg(3)N(2) sample started to release hydrogen from ∼65 °C and gave a material-based hydrogen capacity of ∼11 wt% upon heating to 300 °C. In addition to the improved dehydrogenation kinetics, the 6AB/Mg(3)N(2) sample also showed sat...
متن کاملAmmonia-Borane Complex for Hydrogen Storage
The goal of this project was to develop a high-density hydrogen storage system based on ammonia borane (AB) complex. Due to their high hydrogen capacity, AB hydrides have been employed as disposable hydrogen (H2) sources for fuel cell applications. The objectives of this project were to 1) identify viable amine-borane (AB) complexes for hydrogen storage at ambient conditions, and 2) develop a c...
متن کاملComplete hydrogen release from aqueous ammonia-borane over a platinum-loaded titanium dioxide photocatalyst.
Complete H2 release from ammonia-borane (NH3BH3, AB) in water was achieved by using platinum-loaded TiO2 (Pt/TiO2) via two consecutive reaction steps, i.e., hydrolysis of AB and photocatalytic decomposition of thus formed NH3 in water, under inert conditions at 298 K.
متن کاملA metal-organic framework as a chemical guide to control hydrogen desorption pathways of ammonia borane.
We report that ammonia borane with a high uptake capacity for hydrogen can be encapsulated in a metal-organic framework (MOF) via capillary action, where the MOF functions as a chemical guide to control the hydrogen desorption pathways of ammonia borane by releasing only pure hydrogen, lowering its hydrogen desorption temperature, and suppressing its volumetric expansion during hydrogen desorpt...
