Ag-CeO2/C catalyst material as well as preparation method and application thereof

The invention discloses an Ag-CeO2/C catalyst material and a preparation method and application thereof, and the method comprises the following steps: (1) mixing a carbon carrier material, a silver additive, a cerium additive and a solvent to form a mixed dispersion liquid; (2) volatilizing the solvent in the mixed dispersion liquid so as to form mixed powder; and (3) under an anaerobic condition, heating and reacting the mixed powder so as to obtain the Ag-CeO2/C catalyst material. According to the method, the carbon material is used as a carrier, the silver additive is used as an active substance, the cerium additive is used as a cocatalyst, and the prepared Ag-CeO2/C catalyst material has the advantages of being high in activity, good in catalytic performance and the like. The method has the advantages of low cost, simple operation, short period, and easy realization of industrial stable production. 本发明公开了Ag-CeO2/C催化剂材料及其制备方法和应用，所述方法包括：(1)将碳载体材料、银添加剂、铈添加剂和溶剂混合，以便形成混合分散液；(2)使所述混合分散液中的所述溶剂挥发，以便形成混合粉末；(3)绝氧条件
