中文摘要：

以阳极氧化方法制备的高度有序的TiO2纳米管阵列材料作为催化剂，在波长254nm和365nm的紫外光照射下光催化降解含苯胺水体，并考察了影响苯胺水体光催化降解的各种因素。结果表明，当苯胺浓度为0．33mmol／L、pH=7、紫外光波长λ=254nm和反应时间为120min时，苯胺的降解率可以达到99%；延长反应时间，增加紫外光入射能量和通入一定量空气能够提高催化剂的催化活性；另外苯胺水样中含Fe抖也能有效提高苯胺水样的降解率。

英文摘要：

The high density and well ordered TiO2 nanotube array material was successfully prepared with anodic oxidation method. It was could be application in photocatalytic degradation aniline organic wastewater analog under 254 nm and 365 nm UV irradiation. The results exhibited that the the rate of degradation of aniline reached 99% under the concentration of aniline was 0. 33 mmol/L, pH= 7, intensity of UV irradiation was 254 nm and reaction time was 120 min. The factors that influence the rate of degradation were also investigated. It is be found the reaction time goes on, higher energy of UV irradiation and add air can increase catalytic activity. Furthermore, Fe^3＋ was could effectively increased the rate of photocatalytic degradation.
