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 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 کاملHydrogen generation by electrolysis of liquid ammonia.
Hydrogen gas is generated by the electrolysis of liquid ammonia which has high hydrogen capacity of 17.8 mass%. The metal amides are used as supporting electrolytes to dissolve the amide ion in liquid ammonia. The results presented here indicate that liquid ammonia is promising as an energy medium for hydrogen storage and generation.
متن کاملDehydrogenation of ammonia borane through the third equivalent of hydrogen.
Ammonia borane (AB) has high hydrogen density (19.6 wt%), and can, in principle, release up to 3 equivalents of H2 under mild catalytic conditions. A limited number of catalysts are capable of non-hydrolytic dehydrogenation of AB beyond 2 equivalents of H2 under mild conditions, but none of these is shown directly to derivatise borazine, the product formed after 2 equivalents of H2 are released...
متن کاملAb initio investigation of ammonia-borane complexes for hydrogen storage.
The structural, electronic, and thermodynamic properties of ammonia-borane complexes with varying amounts of hydrogen have been characterized by first principles calculations within density functional theory. The calculated structural parameters and thermodynamic functions (free energy, enthalpy and entropy) were found to be in good agreement with experimental and quantum chemistry data for the...
