Syntheses of novel metal hydrides under high pressure and high temperature

Novel hydrides are synthesized under high pressure and high temperature, where novel hydrogenation reactions are expected to be realized owing to high reactivity of hydrogen fluid. Theoretical calculations predict stabilities of hydrides before experiments, of which results are effectively used for the synthetic studies. In situ synchrotron radiation x-ray diffraction measurement enables us to explore reaction conditions and to reveal the reaction mechanism. In the present paper, synthetic studies of Al₂CuH and Li₄FeH₆ will be presented along with the experimental details.
