"The rate and extent of H-2-release from ammonia borane (AB), a promising, high-capacity hydrogen storage material, was found to be enhanced in ionic-liquid solutions," investigators in the United States report.
"For example, AB reactions in 1-butyl-3-methylimidazolium chloride (bmimCl) (50:50-wt %) exhibited no induction period and released 1.0 H-2-equiv in 67 min and 2.2 H-2-equiv in 330 min at 85 degrees C, whereas comparable solid-state AB reactions at 85 degrees C had a 180 min induction period and required 360 min to release similar to 0.8 H-2-equiv, with the release of only another similar to 0.1 H-2-equiv at longer times. Significant rate enhancements for ...
