Ce/Mo metal oxides with different Ce/Mo molar ratios were synthesized via dielectric barrier discharge (DBD) method for the first time and applied as efficient photocatalysts. The morphology and physicochemical properties of the synthesized samples were characterized by XRD, SEM, BET and XPS. Ce/Mo metal oxides synthesized with Ce(NO3)3·6H2O and (NH4)6Mo7O24·4H2O molar ratio of 4:1 exhibited more surface chemical adsorption of oxygen, which were beneficial to the photocatalytic performance. The degradation rate of 1000 mL (50 mg/L) methyl orange could reach 80% within 18 min under UV-light radiation. Ce/Mo metal oxides exhibited excellent photocatalytic performance and had potential application prospect in dye wastewater treatment.
