摘要
以苎麻纤维为模板,钛酸四丁酯为前驱体,绝对乙醇为溶剂,制备了具有特殊形貌的锐钛矿型二氧化钛,并详细考察了反应时间和钛酸四丁酯浓度对二氧化钛收率的影响,优化了反应条件。XRD结果表明,在优化条件下得到的TiO2为锐钛矿结构。SEM显示,所得TiO2表面具有丰富的褶皱。以活性艳红X-3B的光降解作为探针反应,考察了所制备TiO2的光催化性能,表明其光催化活性较高。
Anatase TiO2 with special morphology was prepared by using ramie fiber as a template,Ti（O^nBu）4 as titanium precursor, and absolute ethanol as a solvent. The influence of reaction time and Ti （O^n Bu）4 concentration on the yield of TiO2 was investigated in detail, and the optimum reaction conditions were obtained. The formation of anatase-phase TiO2 under optimum reaction conditions was confirmed by XRD analysis. SEM images showed that the obtained TiO2 had rich wrinkles. The as-prepared TiO2 had higher photocatalytic activity to the photodegradation of the C.I. reactive red X-3B.
