Transition metal catalysed dehydrogenation of amine-borane fuel blends

Sib Sankar Mal, Frances H. Stephens and R. Tom Baker

Abstract

Mixtures containing ammonia-borane and sec-butylamine-borane remain liquid throughout the hydrogen release process that affords tri(N-sec-butyl)borazine and polyborazylene.

Concentrated solutions with metal catalysts afford >5 wt% H2 in 1 h at 80 °C and addition of (EMIM)EtSO4 ionic liquid co-solvent eliminates competing formation of insoluble linear poly(aminoborane) (EMIM = 1-ethyl-3-methyl-imidazolium).
