Abstract

Abstract: Nano-TiO2 sample was prepared with sol - gel to explore the effect of precursor and solvent on the phase transition of Nano-TiO2 in the preparation. The results show that the beginning temperature of the phase transition is lower when nano-TiO2 is prepared with Ti(OBu)4 than that with TTIP. It is also found that the temperature of the phase transformation of TiO2 varies when different solvents are used, that of phase transition from anatase to Rutile being: t(glycol)<t(methanol)<t(ethanol)<t(butanol).

Key words: TiO2 , Sol-gel , Phase transition

摘要： 采用溶胶-凝胶法制备了TiO2纳米粒子,考察了溶胶-凝胶制备过程中不同前驱体及溶剂对TiO2
从锐钛矿到金红石相变的影响。结果表明,采用钛酸四丁酯(Ti(OBu)4 )为前驱体制备的TiO2相变温度明显低于以
异丙醇钛(TTIP)为前驱体制备的TiO2。不同溶剂制备的TiO2,相变的温度不同,从锐钛矿转化为金红石晶相的温
度为t(乙二醇)<t(甲醇)<t(乙醇)<t(丁醇)。
