چکیده

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 desorption.

Transition metal catalysed ammonia-borane dehydrogenation in ionic liquids.

Significant advantages result from combining the disparate hydrogen release pathways for ammonia-borane (AB) dehydrogenation using ionic liquids (ILs) and transition metal catalysts. With the RuCl(2)(PMe(3))(4) catalyst precursor, AB dehydrogenation selectivity and extent are maximized in an IL with a moderately coordinating ethylsulfate anion.

In Situ High-Pressure and Low-Temperature Study of Ammonia Borane by Raman Spectroscopy

As a potential hydrogen storage material, ammonia borane (NH3BH3) has received extensive investigation among many solid-state chemical hydrides over the past few decades. 4 Ammonia borane is a lightweight molecular complex with a high hydrogen content (19.6 wt %) that exceeds the 2015 U.S. Department of Energy target (9 wt %) for on-board hydrogen storage systems. Consequently, substantial rese...

A rationally designed amino-borane complex in a metal organic framework: a novel reusable hydrogen storage and size-selective reduction material.

A novel amino-borane complex inside a stable metal organic framework was synthesized for the first time. It releases hydrogen at a temperature of 78 °C with no volatile contaminants and can be well reused. Its application as a size-selective reduction material in organic synthesis was also demonstrated.

Exploring Promising Catalysts for Chemical Hydrogen Storage in Ammonia Borane: A Density Functional Theory Study

Density functional theory (DFT) has been applied to study potential ammonia borane (AB) dehydrogenation pathways via new bifunctional ruthenium-based catalysts, alongside their computationally-designed iron-based counterparts (i.e., four catalysts), using the wB97XD (dispersion-included) functional. The efficiency of each catalyst was under scrutiny based on the addition of ammonia borane, with...
