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.
