The invention belongs to the technical field of catalysts, and relates to a catalyst for catalyzing an ammonia synthesis reaction and a preparation method of the catalyst. The catalyst includes a catalytically active substance, the catalytically active substance includes at least one metal or a compound of the metal, metal elements in the metal or the compound are composed of non-radioactive isotopes with components and/or abundance different from natural components and/or natural abundance respectively, and the abundance of at least one non-radioactive isotope changes by 1/20 or more and notless than 20% based on the natural abundance. According to the catalyst for catalyzing the ammonia synthesis reaction and the preparation method of the catalyst, the obtained catalyst can have bettercatalytic performance. 本发明属于催化剂技术领域，涉及一种用于催化合成氨反应的催化剂及其制备方法。所述的催化剂包含催化活性物质，所述的催化活性物质包含至少一种金属或其化合物，该金属或其化合物中的金属元素由组成和/或丰度较天然有所改变的非放射性同位素构成，其中至少一种非放射性同位素的丰度在天然丰度的基础上改变1/20以上且不低于20％。利用本发明的用于催化合成氨反应的催化剂及其制备方法，能够使得到的催化剂具有更好的催化性能。
