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.

Cerium dioxide-supported low-dose PtCu ultrafine alloy catalyst, preparation method and application thereof

The present application is related to a three-dimensionally ordered macroporous oxygen-deficient cerium dioxide catalyst, and a preparation method and an application thereof. The catalyst is prepared by using a polymethyl methacrylate (PMMA) colloidal crystal template method, calcining in a reducing/oxidizing atmosphere, and treating with water vapor, and the prepared catalyst shows an excellent activity and stability in photothermocatalytic purification of typical amospheric pollutants such as styrene, n-hexane, and cyclohexane. The method has the characteristics of cheap and easily available raw materials, simple preparation process, controllable oxygen vacancy, surface acid amount, and acid strength of the obtained material, and excellent photothermocatalytic performance.
