纳米TiO2的离子-水混合热法合成及其光催化性能
The Synthesis of Nano-TiO2 from Mixture of[C2OHMIM] + Cl——water and Its Photocatalytic Activity
摘要
Abstract
Hie nanocrystalline TiO2 was prepared in mixture solvent of ionic liquid [ C2OHMIM] * Cl" and water by hydrothermal method. The samples were characterized by X-ray diffractometer,scanning electron microscopy, Raman spectrometer and UV-Visible spectrometer. The influences of various hydrothermal conditions such as the amount of ionic liquid,reaction temperature and reaction time,on the catalytic activity of TiO2 were investigated. The results show that as-prepared TiO2 is rutile.and its morphology is sphere stacked by nanocrystalline. When TiO2 was prepared under such conditions; the content of ionic liquid being 66.6% .reaction temperature ISO X. .reaction time 24 h,its catalytic activity was the best and the degradation for Rhodanmine B was the highest. Compared with P25, it has higher catalytic activity.关键词
