摘要: 以草酸钛钾(K2TiO(C2O4)2-PTO)为钛源，二甘醇(DEG)和水作为溶剂，制备了TiO2微球和纳米花。利用X射线衍射和扫描电镜对TiO2的形貌和结构进行了分析。利用透射电镜对TiO2纳米花进行了结构分析。结果表明：溶剂中DEG和水的比例对TiO2形貌有着重要的影响，当DEG和水比例为1:1.7时，TiO2呈纳米球状；当DEG和水的比例为1:5时，TiO2呈纳米花结构。XRD结果表明随着溶液中水含量的增加，TiO2结构从纯金红石型变为锐钛矿和金红石混合型。讨论了TiO2形貌随DEG含量变化的机理。
Abstract: TiO2 microspheres and nanoflowers were prepared from PTO, water and DEG by hydrothermal method. The characterizations of TiO2 microspheres and nanoflowers were carried out by X-ray diffraction (XRD), scan electron microscope (SEM) and transmission electron microscope (TEM). The results showed that the TiO2 structures were changed from microsphere to nanoflower with decreasing ratio of DEG/water from 1:1.7 to 1:5. The XRD results showed that the crystal changed from rutile to rutile and anatase. The mechanism of growth mode was also studied.
