摘　　要：以四氯化钛、氢氧化锂为原料,采用模板法,获得前躯体（Li1.81H0.19）Ti2O5·0.262 5TiO2,再通过煅烧,得到纳米钛酸锂（Li4Ti5O12）。最佳制备工艺条件为：模板∶钛（摩尔比）为4∶1,700℃煅烧1 h。采用TEM电镜观测的粒度达到10~100 nm,XRD拟合粒径5~30 nm,比表面积达100~600 m2/g。The precursor（Li1.81H0.19） Ti2O 5 ·0. 262 5TiO2 were prepared by template method with titanium tetrachloride and lithium hydroxide as raw materials,and then to obtain lithium titanate（Li4Ti5O12） by calcination. The optimum preparation conditions were that when molar ratio was 4∶ 1 of template： Ti, and calcined at 700 ℃ for 1 h. The particle size was 10 ~ 100 nm by TEM,the fitting particle size was 5 ~ 30 nm by XRD,and the specific surface area was 100 ~ 600 m2/g.
