Abstract

(Chemical Equation Presented) Looking to the future: The decomposition in solution of a potential hydrogen-storage compound, ammonia borane (AB), was investigated by in situ 11B NMR spectroscopy and ex situ 15N NMR spectroscopy. The reaction was found to be second order in AB withan activation barrier of (25 ± 2) kcal mol-1. The second-order kinetics have implications for the use of solutions containing AB in high concentrations for hydrogen storage.
