The invention belongs to the technical field of catalysts, and relates to a palladium-containing catalyst and a preparation method and application thereof. The catalyst comprises a catalytic active substance, wherein the catalytic active substance comprises metal palladium or a compound thereof; and elemental palladium in the metal palladium or the compound thereof is composed of non-radioactive isotopes with composition and/or abundance which is changed compared with natural composition and/or abundance, and the abundance of at least one non-radioactive isotope is changed by more than 1/20 and not less than 20% on the basis of natural abundance. According to the invention, the prepared palladium-containing catalyst has better catalytic performance. 本发明属于催化剂技术领域，涉及一种含钯催化剂及其制备方法与用途。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金属钯或其化合物，所述的金属钯或其化合物中的钯元素由组成和/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％。利用本发明的催化剂及其制备方法与用途，能够使得到的含钯催化剂具有更好的催化性能。
