The gas-phase photocatalytic oxidation of aniline on a new kind of nano-TiO_2 composite films was investigated. The composite film was prepared on glass fibre with the water glass as binders and dilute H_2SO_4 solution as solidifying reagent, whose surface characters was observed by scanning electron micrograph (SEM). The photocatalytic degradation of aniline on the composite films was carried out in TiO_2/UV system.

The gas-phase photocatalytic oxidation of aniline on a new kind of nano-TiO_2 composite films was investigated. The composite film was prepared on glass fibre with the water glass as binders and dilute H_2SO_4 solution as solidifying reagent, whose surface characters was observed by scanning electron micrograph (SEM). The photocatalytic degradation of aniline on the composite films was carried out in TiO_2/UV system. Some important factors affecting the photodegradation were also studied such as the concentration of TiO_2, the initial concentration of aniline, and water vapour existing. The product of Photocatalytic oxidation was detected by FT-IR. The partial intermediate products were absorbed on TiO_2 surface, which resulted in catalyst deactivation. But when it was irradiated under UV-illumination or solar irradiation for some time, the catalyst could be reused without the loss of catalytic activity.

以水玻璃为粘贴剂,稀硫酸溶液为固化剂,采用涂膜法在玻璃纤维布上制备了TiO2复合膜,并用扫描电子显微镜(SEM)观察了其表面形貌.用纳米TiO2 复合膜作催化剂对大气环境中苯胺的气相光催化氧化进行了研究,考察了催化剂浓度、苯胺的初始浓度、水蒸气等因素对气态苯胺降解率的影响,并用傅立叶变换红外(FT IR)光谱法分析了光催化反应中降解的产物.气相光催化苯胺后的实验结果表明:催化剂表面因中间产物的吸附导致失活,而采用把催化剂放置在太阳光下数日或用紫外灯光照一段时间便可使催化剂活性得到恢复.

Amorphous nanoparticle titania(TiO_2) colloid immobilized on fiber cloth was prepared as a photocatalyst.The surface and structure of the catalyst were characterized by scanning electron micrograph(SEM) and BJH method.Photocatalytic properties of the catalyst for degradation of methyl orange and gaseous aniline under UV-irradiation were investigated.The results showed that the mesoporous TiO_2 was composed of anatase phase and had good activity for photocatalytic degradation.Phenol,benzoquinone,nitrosobenzene...

采用涂膜法直接将非晶态纳米TiO2胶体负载于纤维布上,制备了纳米TiO2光催化剂。采用扫描电子显微镜(SEM)、比表面及孔径分析仪观察了催化剂的表面形貌和结构特征。以甲基橙溶液、气态苯胺为研究对象,考察了负载TiO2纤维布的光催化活性。结果表明,负载于纤维布上的TiO2为锐钛矿型,具有中孔结构,且有较好的光催化降解能力。纳米TiO2光催化降解气态苯胺的中间产物主要有苯酚、苯醌、亚硝基苯和偶氮苯等。推断了其光催化降解历程。
