| 摘 要： | 采用阳极氧化法在钛网上制备了TiO_2纳米管阵列,并利用循环伏安法在纳米管表面沉积Ag,制备出Ag/TiO_2纳米复合材料。采用扫描电子显微镜、X-射线衍射仪、紫外-可见漫反射光谱等方法对复合材料的形貌、结构、光电性能进行了表征,并以2,4-二硝基苯酚为模型化合物考察了沉积Ag对复合材料光催化性能的影响。结果表明,沉积5圈Ag的Ag/TiO_2复合纳米材料光催化性能最佳,在模拟太阳光照射120 min后,2,4-二硝基苯酚可被完全降解。

| Abstract: | TiO2 nanotubes were prepared on titanium mesh by anodic oxidation,and Ag was deposited on the surface of TiO2 nanotubes by cyclic voltammetry,resulting in the Ag/TiO2 nanotubes composite material.Morphology,structure and photocatalytic properties of the composite materials were characterized by scanning electron microscopy (SEM),X-ray diffraction (XRD) and UV-visible diffuse reflectance spectroscopy (DRS).The influences of Ag on the photocatalytic properties of composites materials were investigated by using 2,4-dinitrophenal as model compound.Results indicated that the Ag/TiO2 composite nanomaterial with 5 coils Ag nanoparticales have the best photocatalytic performance,and the 2,4-dinitrophenal could be completely degraded after exposure to the simulated sunlight for120 min. |
