| 摘 要： | 采用一步水解法制备了无定形TiO2(Am-TiO2),并运用X射线衍射、X射线光电子能谱、N2吸附-脱附和紫外-可见漫反射光谱等手段对其进行了表征.结果表明,Am-TiO2具有大的比表面积(216m2/g)和丰富的表面羟基/化学吸附的水.与晶态TiO2相比,Am-TiO2的吸收带边明显蓝移(411nm→378nm),禁...

| Abstract: | Amorphous TiO2 (Am-TiO2) was prepared via a simple step through hydrolysis.The as-prepared Am-TiO2 was characterized by X-ray diffraction,X-ray photoelectron spectroscopy,UV-visible diffuse reflectance spectroscopy,and N2 adsorption-desorption.Large surface area (216 m2/g) and abundant surface hydroxyl group/chemical adsorbed water were observed on Am-TiO2.Compared with crystallized TiO2,the adsorption edge of Am-TiO2 exhibited a blue shift (from 411 to 378 nm).Rapid photo-sensitized degradation of rhodamin... |
