| 摘 要： | 为了提高TiO2薄膜的光催化效率和使用稳定性,采用浸渍涂布法将粉体P-25TiO2负载在泡沫镍基片上,制备泡沫镍基负载P-25薄膜光催化材料,利用XPS和FE-SEM分析了薄膜的晶相和形貌,并考察了不同条件下P-25薄膜对水中喹啉的降解效能。研究发现:P-25薄膜均匀覆盖泡沫镍基片表面,薄膜呈混晶结构,表面呈现微裂痕。实验表明:增大光照强度和曝气量能够明显提高水中喹啉的光催化降解率;低pH有利于水中喹啉的去除;初始浓度和温度不是光催化反应的主控因子;曝气产生的吹脱、扰动和水力紊流效应对光催化反应的影响不明显。结果显示:不改变水溶液温度和pH条件下,P-25薄膜对水中喹啉有良好的去除效果,并可多次重复使用。

| Abstract: | To improve the film's photocatalytic activity and stability in practice,P-25 TiO2 film immobilized on porous nickel substrate was successfully prepared by a facile dip-coating method in situ without any binder.The characteristics of the film were investigated by XRD and FE-SEM.The effects of parameters such as time,temperature,initial concentration,pH values,luminous flux,and aeration on the photocatalysis degradation of quinoline aqueous solution were discussed.It was found that porous nickel was evenly co... |
