中空二氧化钛微球是一种重要的金属氧化物纳米材料，它可以在Ostwald熟化过程的基础上，通过简单的无模板溶剂热法合成。有机溶剂的性质对最终产物的微观结构和性能有很大影响。然而，在中空二氧化钛微球的形成过程中，溶剂类型的影响知之甚少。因此，本文选择甲醇、异丙醇、乙二醇乙二醇丙酮四种有机溶剂作为混合溶剂，采用Ostwald熟化法制备了二氧化钛空心微球。对二氧化钛纳米结构的形貌和结晶度进行了研究。一系列表征结果表明，丙酮具有中等的极性、较低的沸点和较低的粘度，对中空结构的构建有显著影响。这种方法展示了中空结构的巨大可控性。具有中空结构的纳米二氧化钛对罗丹明B具有较强的降解能力，紫外光照射120min后，罗丹明B溶液的残留率几乎为零。
Hollow titanium dioxide (TiO2) microspheres are important metal oxide nanomaterials that can be synthesized via facile template-free solvothermal method based on the Ostwald ripening process. The properties of the organic solvents imposed significant effects on the microstructures and properties of the final products. However, the effects of solvent type were less understood during the formation of hollow TiO2microspheres. So in this work, four organic solvents, namely methanol, isopropanol, ethanediol and actone, were selected to mix with ethanol as the mixed solvents for the solvothermal synthesis of hollow TiO2microspheres based on the Ostwald ripening process. Special attentions were paid to the morphology and crystallinity of TiO2nanostructures. A series of characterization results showed that acetone had significant effects on the construction of hollow structures due to its moderate polarity, low boiling point and viscosity. This method demonstrated the great controllability of the hollow structures. The TiO2nanostructures with hollow structures exhibited an enhanced performance for degradation of Rhodamine B. When irradiated with ultraviolet light for 120 min, the residual rates of RhB solutions were almost zero.
