摘　　要：采用水热法,在温和的条件下制备了具有较高光催化活性的CeO2 TiO2复合光催化剂,在太阳光照射下以罗丹明B的光降解为模型反应研究了其光催化活性。结果表明,适量Ce的掺杂能有效提高TiO2的日光催化活性。用FT IR、TG DTA和XRD等进行了性能表征。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.
