摘要： An ammonia synthesis catalyst having high activity is obtained by having a two-dimensional electride compound having a lamellar crystal structure such as Ca 2 N support a transition metal. However, since the two-dimensional electride compound is unstable, the stability of the catalyst is low. In addition, in cases where a two-dimensional electride compound is used as a catalyst support, it is difficult to shape the catalyst depending on reactions since the two-dimensional electride compound has poor processability. A composite which includes a transition metal, a support and a metal amide compound, wherein the support is a metal oxide or a carbonaceous support; and the metal amide compound is a metal amide compound represented by general formula (1). M(NH 2 ) x ···(1) (In general formula (1), M represents at least one metal atom selected from the group consisting of Li, Na, K, Be, Mg, Ca, Sr, Ba and Eu; and x represents the valence of M.)

摘要： The present invention provides a catalyst substance that is stable and performs well in the synthesis of ammonia, one of the most important chemical substances for fertilizer ingredients and the like. The catalyst substance exhibits catalytic activity under mild synthesis conditions not requiring high pressure, and is also advantageous from a resource perspective. Further provided is a method for producing the same. This catalyst comprises a supported metal catalyst that is supported on a mayenite type compound including conduction electrons of 10 15 cm -3 or more and serving as a support for the ammonia synthesis catalyst. The mayenite type compound used as the support may take any form, including that of powder, a porous material, a sintered body, a thin-film, or a single crystal. Use of this catalyst makes it possible to increase the electron donating ability toward a transition metal, and to promote ammonia synthesis by reacting nitrogen and hydrogen as starting materials on the catalyst under low reaction pressure between about 10kPa and 30MPa at reactive temperature between 100 and 600°C.
