Abstract

For this study, the synthesis of TiO nanomaterials was performed via a novel sol-gel method employing titanium butoxide as a metal precursor, Pluronic F127 as a templating agent, toluene as a swelling agent, and acidic water or ethanol as the reaction solvents. The method was designed by tailoring certain reaction parameters, such as the sequence of toluene addition, magnetic stirring, the type of reaction solvent, and the calcination conditions. Analysis of the specific surface area and porosity was carried out via N physisorption, whereas the morphological features of the solids were investigated via transmission electron microscopy. The crystalline structure of both the dried powders and the calcined materials was evaluated using X-ray diffraction analysis. It transpired that the different phase compositions of the solids are related to the specific synthesis medium employed. Under the adopted reaction conditions, ethanol, which was used as a reaction solvent, promoted the local arrangement of dispersed anatase particles, the specific arrangement of which does not lead to rutile transformation. Conversely, the use of water alone supported high-particle packing, evolving into a rutile phase. The photodegradation of Rhodamine B was used as a target reaction for testing the photocatalytic activity of the selected samples.

摘要

在本研究中,TiO纳米材料的合成是通过一种新型溶胶-凝胶法进行的,该方法使用丁醇钛作为金属前驱体,普朗尼克F127作为模板剂,甲苯作为溶胀剂,酸性水或乙醇作为反应溶剂。该方法是通过调整某些反应参数来设计的,如甲苯添加顺序、磁力搅拌、反应溶剂类型和煅烧条件。通过N物理吸附对比表面积和孔隙率进行分析,而通过透射电子显微镜研究固体的形态特征。使用X射线衍射分析评估干燥粉末和煅烧材料的晶体结构。结果表明,固体的不同相组成与所采用的特定合成介质有关。在所采用的反应条件下,用作反应溶剂的乙醇促进了分散的锐钛矿颗粒的局部排列,其特定排列不会导致金红石转变。相反,单独使用水支持高颗粒堆积,演变成金红石相。罗丹明B的光降解用作测试所选样品光催化活性的目标反应。
