The invention provides an ammonia decomposition catalyst and a preparation method and application thereof. The catalyst comprises an active component, a carrier and an auxiliary agent; the active component is one or both of nickel and ruthenium, and the carrier is Yttria-stabilized zirconia or BaCe 0.7 Zr 0.1 Y 0.2 O 3-δ , the auxiliary agent is one or more of alkali metal oxides, alkaline earth metal oxides, and rare earth oxides, and the catalyst adopts yttria-stabilized oxidation Zirconium or BaCe 0.7 Zr 0.1 Y 0.2 O 3-δ is used as the carrier of the ammonia decomposition catalyst, and the carrier can form a strong interaction with the active component, weakening the interaction between the active component and the decomposition products of NH 3 NH 2 , N or H. The interaction between them is beneficial to the desorption of the products N 2 and H 2 , improves the low temperature activity of the catalyst, achieves better ammonia decomposition effect, and improves the treatment efficiency of ammonia gas. |
