| Abstract: | The photocatalyst CeO_2-TiO_2 with higher photocatalytic activity is prepared by hydrothermal method in mild condition, its photocatalytic activity is investigated using the photocatalytic degradation of Rhodamine B as a model reaction in sunlight. The result showed that sunlight photocatalytic activity of TiO_2 increased greatly owning to doping CeO_2, and also was characterized by FI-IR,TG-DTA and XRD. |
