| 简介 |
The purpose of the present invention is to provide an ammonia decomposition catalyst that has high mechanical strength and that makes it possible to efficiently decompose ammonia into hydrogen and nitrogen, and a method for producing oxygen and nitrogen using the ammonia decomposition catalyst. The ammonia decomposition catalyst according to the present invention is characterized by containing : cobalt (A); one or more rare-earth elements (B) selected from cerium, yttrium, and lanthanum; one or more alkali earth metal elements (C) selected from barium and strontium; zirconium (D); and a calcium compound (E), the ammonia decomposition catalyst moreover being characterized in that the cobalt (A), the rare-earth element (B), the alkali earth metal element (C), and the zirconium (D) are included as metals or as oxides. |
