水素貯蔵材料開発の為の高圧合成法による新規合金・水素化物の探索

抄録

Hydrogen storage technique is one of the key technologies to create hydrogen energy society. In this article, high-pressure synthesis of novel alloys and hydrides for hydrogen media was reviewed. New intermetallic compounds and hydrides were synthesized by using multi-cubic anvil system. For example, new MgNi intermetallic compound with a CuTi type structure was synthesized at 6 GPa and 300℃. This compound was stable in ambient pressure and hydrogenated/dehydrogenated reversibly.
