摘要： The present invention is to provide an electron or hydride ion intake/release material comprising a lanthanoid oxyhydride represented by the formula Ln(HO) (in the formula, Ln represents a lanthanoid element) or an electron or hydride ion intake/release composition comprising at least one kind of lanthanoid oxyhydride; a transition metal-supported material wherein a transition metal is supported by the above electron or hydride ion intake/release material or electron or hydride ion intake/release composition; and a catalyst comprising the transition metal-supported material. The electron or hydride ion intake/release material or electron or hydride ion intake/release composition according to the present invention has a higher ability for intake/release of electron or hydride ion than that of a conventional hydride-containing compound, and can be used effectively as a catalyst such as a catalyst having excellent ammonia synthesis activity by supporting a transition metal thereon.
