摘　　要：通过光还原法合成了银负载二氧化钛(Ag/TiO2)复合材料,测定了其作为光催化剂降解罗丹明B的性能。考察了不同煅烧温度处理对其光催化性能以及润湿性能的影响。结果表明适当温度下的热处理不但可以改善样品的润湿性能,同时可以提高其光催化降解污染物的性能。Silver loaded titanium dioxide （Ag/TiO2 ）composite material was synthesized by photoreduction method. The photocatalytic activity of Ag/TiO2 on photocatalytic degradation of rhodamine B was tested. The composite material was annealed at various temperatures,and the photocatalytic and wettability were determined. The results show that wettability and photocatalytic performance of the composite material can be improved when it is annealed at an appropriate temperature.
