摘　　要：以TiCl3为前驱物,NaCl为矿化剂,十六烷基三甲基溴化铵（CTAB）为表面活性剂,用水热法制备出了纳米TiO2微球。用XRD和SEM对制备的样品进行表征。结果表明：微球为金红石型,直径约为1～5μm,微球由纳米棒放射状组装而成,纳米棒长度约为500nm,直径约为40nm。并研究了表面活性剂浓度、矿化剂浓度、反应时间等实验条件对微球的影响。Using TiCl3 as precursor,NaCl as mineralizer,CTAB as surfactant,TiO2nano-microspheres were synthesized by hydrothermal method.XRD and SEM were employed to characterize the crystal structure and morphology of the microspheres.The results indicated that the microspheres were rutile with diameter of about 1～5μm.The microspheres were composed of radially aligned nanorods with diameters of about 40 nm and lengths of 500 nm.The influences of the concentration of surfactant,the concentration of mineralizer and the reaction time were also researched.
