摘　　要： 利用木质素磺酸钠,采用直接沉淀法制备了纳米二氧化钛(TiO_2)材料。采用XRD、SEM手段对所制备的材料进行分析表征,发现所制备的二氧化钛材料(SLS-TiO_2)具有球形粒子形貌,且为锐钛矿结构。以亚甲基蓝为降解对象进行光催化性能测试,光催化研究表明我们所制备的二氧化钛具有很高的光催化活性,其中1.0 g-SLS-TiO_2样品的光催化活性最高,对亚甲基蓝的光催化降解效率可达97.6%。 Yitanium Dioxide was prepared with the assistant of sodium lignosulfonate by direct precipitation method. The XRD and SEM were used te characterize the structure and morphology of the prepared titanium dioxide. And it found that our titanium dioxide is well dispersed sphere particles with futile structure. Photocatalytic performance was studied by methylene blue. The results showed that the prepared TiO2 had high photocatalytic activity. The degradation efficiency can reach as high as 97.6 % when 1.0 g sodium lignosulfonate was used.
