| 제목 | Preparation of Morphology Controllable TiO2 Nanoparticles from Ammonium Hexafluorotitanate by Aqueous Solution Routes |
| 초록 | TiO2 is one of the most widely researched semiconducting metal oxides and it often used in various industrial fields such as photocatalyst, Li ion battery, solar cell (DSSCs/QDSSCs), sensor, pigments, cosmetics because of its unique structure, nontoxicity, low cost, chemical properties. Up to now, numerous studies have revealed that the performance of TiO2 nanostructures is generally determined by the physical properties such as crystal structure, surface, morphologies and phase. Moreover, considerable efforts have been devoted to developing various TiO2 nanostructure and morphologies of 0D to 3D and other hierarchical nanostructures using solution-based routes including sol-gel, precipitation, hydrothermal, solvothermal and so on. Herein, various TiO2 nanostructures were fabricated via facile precipitation and hydrothermal approach with ammonium hexafluorotitanate ((NH4)2TiF6, AHFT) as precursor. Field emission scanning electron microscope (FESEM) and transmission electron microscopy (TEM) result showed that flower-like, hollow sphere, nanowire and nanotube of TiO2 easily obtained. Also, we evaluated the effect of various experimental conditions such as temperature, reaction time, solvent, etc. Based on the results, we propose the synthesis possibility of TiO2 nanostructure using AHFT as raw material. |
