摘要： 报道了一种制备金红石相纳米二氧化钛的新方法.即以四氯化钛作为原料,通过加入特殊的有机添加剂,利用简单的水解法,在较低温度下制备了金红石相纳米二氧化钛粒子.利用X-射线衍射(XRD)、场发射扫描电镜(FESEM)及热重差热(TGDTA)分析等方法对产物的形貌以及添加剂的用量和煅烧温度对产物晶相和粒径的影响进行了研究.结果表明,添加剂的用量对二氧化钛产物中金红石相的含量有显著影响,当添加剂的用量为0.5 g/mL水时可直接水解得到完全的金红石相;经过400 ℃的煅烧,即可得到结晶良好的金红石相纳米二氧化钛球形粒子,晶粒径约为40~50 nm.

Abstract: This paper reported a novel method to prepare rutile TiO2 nanoparticles. When TiCl4 solution hydrolyzed, rutile TiO2 nanoparticles can be prepared
at low temperature by adding a kind of organic additive into TiCl4 solution.
XRD, FE-SEM and TG-DTA were used to analyze the influence of the amount of organic additives and the calcining temperature on the phase and particle
size of prepared nanoparticles. It was found that the best additive amount is
0.5 g/100 mL H2O, and the best calcining temperature is about 400 ℃. Being treated at the best condition, rutile TiO2 nanoparticles (40~50 nm) can be obtained.
