It was observed that approximately 1 equiv. of hydrogen was evolved from the doped ammonia borane samples at a temperature as low as 59 °C. Moreover, the catalytic dehydrogenation did not present any induction period, undesirable byproduct borazine, or sample forming. Electron paramagnetic resonance (EPR) characterization revealed that Co in a partially reduced state is the active species in the catalytic dehydrogenation of ammonia borane. %I ACS Publications
