碳纤维@二氧化钛纳米线@Ag的制备及其光催化性能

Preparation and Photocatalytic Properties of Carbon Fibers@TiO 2-nanowires@Ag

采用“预涂层”–“生长”–“负载”三步法制备得到碳纤维@二氧化钛纳米线@Ag复合光催化材料。通过场发射扫描电子显微镜、X射线衍射光谱和X射线光电子能谱对该复合材料进行分析表征,并对其光催化性能进行测定。结果表明:TiO2纳米线在碳纤维表面分布均匀且致密,Ag纳米颗粒在TiO2-NWs表面分布较为均匀。该复合材料对亚甲基蓝表现出较好的光催化效果和稳定性。

Carbon fibers@TiO 2-nanowires@Ag was prepared by a“pro-coating”-“growth”-“loading”method.The composite was characterized with field emission scanning electron microscope,X-ray diffractometer and X-ray photoelectron spectrometer,and its photocatalytic properties were determined by degrading methylene blue.The results showed that the entire surfaces of CFs are uniformly coated with dense and vertically aligned TiO 2 nanowires,while Ag nanoparticles were loaded on the surfaces of TiO 2 nanowires.The composite has good photocatalytic activity and photostability to degrade methylene blue.
