Abstract
The present invention provides a cerium dioxide-supported low-dose PtCu ultrafine alloy catalyst, a preparation method and an application thereof, which belongs to the fields of environmental catalysis and preparation of catalyst materials. Metal-state PtCu ultrafine alloy particles are prepared by an oleylamine method, and then a cerium dioxide support is immersed into an n-butylamine solution of PtCu ultrafine alloy, centrifuged, washed with alcohol, and dried to obtain the cerium dioxide-supported low-dose PtCu ultrafine alloy catalyst. The catalyst obtained has excellent activity and stability in simultaneously degrading atmospheric VOCs and soot under a photothermocatalytic condition. There are the characteristics of simple preparation process method, very low Pt dosage, high utilization rate, and excellent photothermocatalytic performance.
