Platinum catalyst for propane catalytic combustion and preparation method and application thereof

The invention relates to a platinum catalyst for propane catalytic combustion and a preparation method and application thereof, the catalyst takes Nb2O5 as a carrier, Pt as an active component and W as an auxiliary agent, the loading amount of Pt accounts for 0.5-2% of the mass of the carrier, and the loading amount of W accounts for 1-15% of the mass of the carrier. The preparation method comprises the following steps: synthesizing an Nb2O5 carrier by a sol-gel method, loading a certain content of Pt and W precursors on the surface of the carrier by an isovolumetric co-impregnation method, and then standing, drying and roasting in high-temperature air to obtain the Pt-xW/Nb2O5 catalyst. Compared with the prior art, the catalyst has the advantages of high activity, high thermal stability, high water and CO2 resistance and the like, and the preparation method is simple, high in repeatability, environment-friendly and safe. 本发明一种用于丙烷催化燃烧的铂催化剂及其制备方法和应用，该催化剂以Nb2O5为载体，Pt为活性组分，W为助剂，Pt的负载量为占载体质量的0.5-2％，W的负载量为占载体质量的1
