介孔二氧化钛的制备及其光催化性能
Preparation of Mesoporous Titania and its Photocatalytic Performance
摘要
Abstract
Mesoporous titania was synthesized via a sol-gel method by using isopropyl titanate as the precursor and cetyl trimethyl ammonium bromide as the template. X-ray diffraction(XRD),scanning electron microscope(SEM),transmission electron microscope(TEM)and BET surface area measurement were used to characterize the product. Methyl blue was used as the object of photocatalytic degradation,and the influence of TiO2 dosage and different kinds of template on the photo-catalytic performance was studied. The result indicated that the degradation rate of methyl blue could reached 99.1%within 4,h when the amount of catalyst was 0.50,g/L. Preparation of mesoporous titania using cetyl trimethyl ammonium bromide as template gave the best photocatalytic activity among the three kinds of template.关键词
