| 摘 要： | 为提高纳米TiO_2的光催化降解性能和稳定性,先采用微波-溶胶法制备Dy/TiO_2溶胶,再以高硅氧玻璃纤维编织体为载体,经过浸渍-提拉法制备具有高催化性能的高硅氧纤维负载纳米Dy/TiO_2薄膜。采用XRD,SEM,PL,EDS,XPS等仪器对薄膜的物相、表面形貌结构、表面元素组成及薄膜的稳定性进行表征,并且研究预处理液和涂覆方式对高硅氧纤维薄膜的影响。另外以甲基橙为目标降解物,考察样品的光催化性能。结果表明:以高硅氧玻璃纤维编织体为载体制备的Dy/TiO_2薄膜稳定性很好;经5次涂覆后,Dy/TiO_2高硅氧纤维薄膜对甲基橙的降解率在30min后达到94%。

| Abstract: | In order to improve the photocatalytic degradation performance and stability of nano TiO2, Dy doped TiO2 supported on high silica glass fiber was prepared by microwave-sol method combined with dip-coating method.The samples were analyzed by XRD,SEM,PL,EDS,XPS and other equipments for phase composition of films,surface topography, surface elements and the stability of films.And the effects of pretreatment solution and coating method on the high-silica fiber film were investigated.In addition, the photocatalytic performance of the sample has been investigated by degrading methylene blue.The results show that the catalytic stability of Dy doping TiO2 nanofilms supported on high silica glass fiber can be improved and the degradation of methyl orange can reach 94% in 30min after 5 times of coating treatment. |
