| 摘 要： | 通过三嵌段的共聚物做模板制备了一系列具有不同锆含量、强酸性的介孔硅材料,获得的样品通过x射线衍射分析、透射电镜分析、氮气吸附脱附、紫外可见光谱、热重分析等技术进行了表征.研究结果发现,当样品中硅和锆的物质的量比大于4时,锆物种能被完全引入到有序介孔硅结构的骨架中;然而,当样品中硅和锆的物质的量比小于4时,会出现一个由无... |

| Abstract: | A series of mesoporous sulfated silica-zirconia materials with various Si/Zr molar ratios(2.0~5.0) have been prepared using tri-block copolymer as a template,which was characterized by X-ray diffraction,TEM,nitrogen adsorption-desorption,UV-Vis diffuse reflectance spectroscopy,infrared spectroscopy,thermal gravimetric analysis,and catalytic reactions.XRD patterns displayed that ordered mesoporous sulfated silica-zirconia materials were obtained when the molar ratio of Si/Zr was more than 4.0.When the molar ... |
