离子液体修饰溶胶–凝胶法制备介孔二氧化钛
Preparation of Mesoporous TiO2 by Ionic Liquid Modified Sol-Gel Method
摘要
Abstract
The mesoporous anatase TiO2 material was prepared （[C4MIM]BF4） by an ionic liquid modified sol-gel method using tetrabutyl titanate as a titanium source. The prepared TiO2 was characterized by N2-physisorption, Fourier transform infrared spectro- scope, X-ray diffractometer, and transmission electron microscope, respectively. The results showed that the mesoporous sample TiO2 prepared with the addition of ionic liquid of 2.5mL and calcined at 300 exhibited large specific surface area （178.133 m^2/g）, and particles of the sample TiO2 was approximately 20 nm, The photocatalytic degradation experiment of methyl orange indicated that the sample TiO2 prepared added ionic liquid of 2.5 mL exhibit a higher photocatalytic activity. Product calcined at 700 ℃ is still anatase crystal phase, indicating that the product has good thermal stability.关键词
