摘要
以硝酸为催化剂,钛酸丁酯为前驱物,用溶胶-凝胶法制备TiO2凝胶,研究了不同的掺水量、硝酸含量、反应温度、搅拌速度等反应条件下的凝胶过程,采用X射线衍射和透射电镜对纳米粒子的性能进行分析,找出制备纯度较高的锐钛矿型的纳米TiO2粉体的最佳工艺条件。
With HNO3 as activator, Ti（ OBu）4 as precursor, TiO： gelation was prepared by sol-gel method. By studying the gel process under different conditions such as H2O content, nitric acid content, hydrolysis temperature and churning speed. The properties of the nanometer-sized particles were analysised by XRD and TEM. The optimum process conditions to prepare nano- TiO2 of anatase with high purity was gained.
