SnO_2-TiO_2复合氧化物的制备、表征及日光催化研究

Study of preparation and sunlight catalytic of SnO_2-TiO_2 photocatalyst

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SnO2-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,掺Sn 0.3%的TiO2日光催化活性比纯TiO2的明显提高。用FT-IR、TG-DTA和XRD等进行了性能表征。

The photocatalyst SnO2-TiO2 with higher photocatalytic activity is prepared by hydrothermal method in mild condition,it＇ s 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 TiO2 increased greatly owning to doping SnO2 （0.3%）, and also was characterized by FI-IR, TG-DTA and XRD.
