Abstract
It is provided that the catalyst shows a high activity in an ammonia decomposition reaction and can efficiently decompose ammonia into hydrogen and nitrogen. The catalyst for decomposing ammonia of the present invention comprises at least one element (component (A)) selected from the elements of groups 6 to 10 of the long-form periodic table, and an oxide and/or complex oxide of at least one element (component (B)) selected from the elements of groups 2 to 5 and groups 12 to 15 of the long-form periodic table, wherein the calculated specific surface area (S2) of the component (A) is 20 m2/g or larger, and the ratio (S2/S1) of the calculated specific surface area (S2) of the component (A) to the specific surface area (S1) of the catalyst per se is 0.15 to 0.85.
