| abstract |
The invention belongs to the technical field of catalysts, and relates to a silver-containing catalyst, and a preparation method and application thereof. The catalyst comprises a catalytic active substance, wherein the catalytic active substance comprises metallic silver or a compound thereof, the silver element in the metallic silver or the compound thereof is composed of non-radioactive isotopes of which the composition and/or the abundance is changed from natural abundance, and the abundance of at least one non-radioactive isotope is changed from 1/20 to 20 percent on the basis of the natural abundance. By utilizing the catalyst, the preparation method and the application thereof, the obtained silver-containing catalyst has better catalytic performance. |
