| 摘 要： | 以壳聚糖Chitosan（β-1，4-聚-葡萄糖胺）为模板剂，用溶胶-凝胶70℃水浴条件下制备纳米TiO2粉体．采用透射电镜（TEM）、X射线粉末衍射（XRD）、傅立叶红外光谱（FT—IR）以及紫外．可见光谱（UV—vis）等手段对产物进行了分析和表征．结果表明：加入壳聚糖后，所得纳米TiO2产物由锐钛矿相构成，粒子分散性较好．光催化实验结果表明，所得产物在日光下对有机染料罗丹明B有较好的催化降解作用．

| Abstract: | In the presence of the chitosan template, the TiO2 nanoparticles with high photocatalytic activity were prepared by a sol-gel water bath process. The product was characterized by TEM, XRD, FT-IR and UV-vis spectra. The results show that the TiO2 nanoparticles as-obtained are composed of anatase crystal phase, with a good dispersion . the photocatalytic activity of the TiO2 nanoparticles was studied by photodegradating organic dye Rhodamine B on sun light. |
