摘要：
Pure ZnO, Ag-doped ZnO, Ce-doped ZnO, and co-doped ZnO (Ag-Ce/ZnO) nano-photocatalysts were synthesized by the hydrothermal method. Compared with pure ZnO, Ag-doped ZnO, Ce-doped ZnO, and Ag-Ce/ZnO exhibited excellent photocatalytic performance due to their superior optical and photoelectrochemical properties. Photodegradation experiment results revealed that the Ag-Ce/ZnO photocatalysts could degrade 97% of RhB dye within 30 min. Further, it was proved that the superoxide radicals played an active role in the photodegradation reaction. A possible mechanism of Ag-Ce/ZnO degradation was proposed.
