| abstract |
The invention discloses a low-temperature ammonia decomposition catalyst for hydrogen production and a preparation method and application thereof. The catalyst comprises a carrier, an active component and a selectively added co-catalyst; the active component is ruthenium, and the co-catalyst is an alkali metal, One or both of alkaline earth metal and rare earth metal oxides, the carrier is metal composite oxide M 2 Ce 2 O 7 , and M refers to La, Sm or Y. The invention adopts the citric acid complex method to prepare the metal composite oxide M 2 Ce 2 O 7 , and then supports ruthenium to prepare the Ru/M 2 Ce 2 O 7 catalyst. The catalyst prepared by the invention has the advantages of high mechanical strength, good thermal stability, simple preparation process, low production cost and high low-temperature catalytic activity, and has good industrial application prospects. |
