| 摘 要： | 以TiCl4为前驱体,采用溶胶-凝胶自燃合成的方法制备了同时掺杂Ce3 ,Fe3 ,Zn2 的纳米TiO2粉体.用X光衍射法对粉体的相组成进行了表征.用正交试验研究方法考察了Fe/Ce、(Fe Ce)/Ti、柠檬酸/Ti(物质的量的比)、煅烧温度、煅烧时间等对产物相组成的影响.结果表明,柠檬酸/Ti,煅烧温度,(Fe Ce)/Ti对产物相组成具有显著影响.

| Abstract: | Titania nanoparticles co-doped with Ce~(3 ),Fe~(3 ),Zn~(2 ) were prepared by sol-gel self-combus- tion synthesis with TiCl_4 as the precusor.The products were characterized by X-Ray Diffraction(XRD). The effects of Fe/Ce,(Fe Ce)/Ti,citric acid/Ti(in mole ratio),calcining temperature and time on phase composition were investigated by the orthogonal experimental method.The results showed that citric acid/Ti,calcining temperature and(Fe Ce)/Ti affect dominantly on phase composition of the products. |
