It provides a dehydrogenation catalyst of ammonia borane-based compound and a method for producing hydrogen using the same. The dehydrogenation catalyst according to the present invention is a dehydrogenation catalyst of an ammonia borane-based compound, which is a central transition metal selected from Ni, Co, Cu, Mn, and Fe, and a counter anion which is non-coordinated to the center transition metal. ) And an ancillary ligand coordinating to the central transition metal. The counter anions are BF 4 -, SbF 6 - and PF 6 - is at least one selected from the. By using such a dehydrogenation catalyst, 2.3 equivalents or more of hydrogen can be generated from the ammonia borane compound, which is a hydrogen storage body, with high efficiency at low temperature, for example, in a short time within 60 seconds, and is excellent in regeneration. |
