High-pressure synthesis of novel alloys and hydrides for hydrogen storage media

Abstract

Hydrogen storage technique is one of the key technologies to create hydrogen energy society. In this article, highpressure 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°C. This compound was stable in ambient pressure and hydrogenated/dehydrogenated reversibly.
