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 کاملFacile Uptake and Release of Ammonia by Nickel Halide Ammines
Although major difficulties are experienced for hydrogen- storage materials to meet performance requirements for mobile applications, alternative fuel cell feedstocks such as ammonia can be stored in the solid state safely at high capacity. We herein describe the NiX2 -NH3 (X=Cl, Br, I) systems and demonstrate their exceptional suitability for NH3 storage (up to 43 wt % NH3 with desorption that...
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 کاملZIF-8 immobilized nickel nanoparticles: highly effective catalysts for hydrogen generation from hydrolysis of ammonia borane.
Highly dispersed Ni nanoparticles have been successfully immobilized by the zeolitic metal-organic framework ZIF-8 via sequential deposition-reduction methods, which show high catalytic activity and long durability for hydrogen generation from hydrolysis of aqueous ammonia borane (NH(3)BH(3)) at room temperature.
