The present invention relates to a method for regenerating dehydrogenated ammonia borane (polybazalin) after use by using a supercritical fluid with ammonia borane, and is carried out by a simple process using a supercritical fluid, so that process efficiency and regeneration yield are excellent , It is possible to solve the low regeneration yield problem in the conventional ammonia borane regeneration process and the low process efficiency due to the complicated process, and it is possible to effectively reuse the expensive ammonia boran, which is useful in the field of hydrogen gas storage material and fuel cell have. |
