Abstract: Improving effects of LiH and Co-catalyst on the dehydrogenation of Li 4BN3H10 were investigated in this work. It was found that 9.6 wt % or 5 equiv. moles of H2 can be evolved from the promoted sample at 250 °, which is 110 ° lower than that of pristine Li4BN3H10. More importantly, NH3 emission is depressed dramatically, with its concentration in hydrogen decreasing from 12 mol % to 0.008 mol % (or 80 ppm). Melting of Li 4BN3H10 is essential for one unit of LiNH 2 fleeing from the structure and interacting with LiH to evolve 1 equiv. mole of H2, in the meantime, Co-catalyst takes effect on the dissociation of remaining Li3BN2H8, resulting in the evolution of another 4 equiv. moles of H2 at temperatures close to that of LiNH2-LiH. © 2011 American Chemical Society.
