摘  要:以钛酸四丁酯为钛源,采用离子液体([C4MIM]BF4)修饰溶胶–凝胶法制备锐钛矿相介孔二氧化钛光催化材料。采用氮气吸附–脱附、红外光谱、X射线衍射以及透射电子显微镜等检测技术对样品进行表征,以甲基橙水溶液为降解对象,在紫外光(λ = 468 nm)下,考察了制备样品的光催化活性。结果表明:当离子液体加入量为2.5 mL时,300 ℃焙烧的介孔二氧化钛具有较大的比表面积(178.133 m2/g),所得样品粒径约为20 nm,此时样品具有较高的光催化活性。700 ℃焙烧仍为锐钛矿相,表明产物具有好的热稳定性。

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 spectroscope, X-ray diffractometer, and transmission electron microscope, respectively. The results showed that the mesoporous sample TiO2 prepared with the addition of ionic liquid of 2.5 mL and calcined at 300 ℃ exhibited large specific surface area (178.133 m2/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.
