AlH₃の実用水素貯蔵材利用を目指した高圧研究

抄録

  Aluminum tri-hydride (AlH₃) is promising as a hydrogen storage material. Hydrogenation and dehydrogenation mechanism of aluminum still remain unclear and fundamental study of the Al-H system is required to utilize AlH₃ as a practical hydrogen storage material. Aluminum is hydrogenated under high pressure and high temperature to clarify the reaction mechanism. The hydrogenation and dehydrogenation process is investigated using an energy-dispersive and an angle-dispersive in situ x-ray diffraction system.
