PROBLEM TO BE SOLVED: To provide a composition which enables ammonia to be manufactured at high yield under low pressure conditions, as well as a method for manufacturing ammonia using this composition.SOLUTION: There is provided the composition blending (1) ruthenium, an alloy containing ruthenium or a chemical compound containing ruthenium, (2) a chemical compound containing lanthanoid, and (3) a basic cocatalyst and/or a porous metal complex. The chemical compound containing the lanthanoid is preferably a lanthanoid oxide. The basic cocatalyst is preferably an alkali metal oxide, an alkali metal hydroxide, an alkaline earth metal oxide or an alkaline earth metal hydroxide. The porous metal complex preferably contains at least one kind of metal selected from the group consisting of zinc, copper, magnesium, aluminum, manganese, iron, cobalt and nickel. The method for manufacturing ammonia includes reacting nitrogen with hydrogen using the composition as a catalyst. |
