Hydrogenation/Dehydrogenation reaction

Patent Pending PROBLEM TO BE SOLVED: To accelerate hydrogenation or dehydrogenation reaction rate by controlling the thermal vibration of the covalent bond and the ionic bond from outside for hydrides of the inorganic complex system such as the borohydride system having B-H bond, such as LiBH<SB>4</SB>or Zn(BH<SB>4</SB>)<SB>2</SB>, which is noticed as a hydrogen storage medium, the amide-imide system having N-H bond, such as LiNH<SB>2</SB>or Mg(NH<SB>2</SB>)<SB>2</SB>, or the alanate system having Al-H bond, such as LiAlH<SB>4</SB>or NaAlH<SB>4</SB>, metal hydrides such as TiH<SB>2</SB>MgH<SB>2</SB>, and the mixed phases of the hydrides of the inorganic complex system and the metal hydrides.
