A 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...
متن کاملSynthesis of Nanoporous Metal Organic Framework MIL-53-Cu and Its Application for Gas Separation
MIL-53-Cu has been synthesized hydrothermally and has been used for the first time for gas separation. MIL-53-Cu shows adsorption capacities of 8.1, 0.7 and 0.5 m.mol/g, respectively, for CH4, CO2 and H2 at 30 bar and 298 K. The high CH4 adsorption capacity of MIL-53-Cu maybe attributed to the high pore volume and large number of open metal sites....
متن کاملCO2 capture and separation using metal-organic frameworks: effect of amine- functionalization and framework flexibility
Reducing the CO2 levels in the atmosphere is one of the emerging challenges for human society. It is commonly accepted that CO2, as a greenhouse gas, is partly responsible for climate changes. It is thus important to reduce those CO2 levels in every possible way. This can be achieved in different manners, for example by decreasing CO2 emission by developing energy efficient processes with a red...
متن کاملHydrogen 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...
