The invention provides a preparation method of a non-noble metal CDPF catalyst based on sodium metavanadate, which takes sodium metavanadate as a catalytic active component, and the catalytic active component is supported and dispersed on a cordierite carrier through a supporting component to prepare an integral catalystThe preparation method is simple, and the prepared catalyst has large specific surface area, good combustion performance and high durability. The catalyst coating takes sodium metavanadate as a catalytic active component to react with O 2 Activating to generate active oxygen, and further reacting with PM; the catalytically active component is supported and dispersed on a cordierite carrier to produce a monolithic catalyst by a supporting component which not only increases the contact area of the catalytically active component with the PM but also prevents the agglomeration effect of the catalytically active centers. |
