| 摘 要： | 以P123为模板剂,正硅酸乙酯（TEOS）为硅源,氧氯化锆和硝酸亚铈为无机前驱盐,3-巯基丙基-三甲氧基硅烷（MPTMS）为硅烷化试剂,通过一步共缩聚法合成了巯基功能化短孔道有序介孔材料HS-Zr-Ce-SBA-15（HS-ZCS）。采用红外光谱（FT-IR）、小角X射线衍射（LXRD）、透射电镜（TEM）、扫描电镜（SEM）、N2吸附/脱附、热重分析（TG）等手段对HS-ZCS进行了表征。结果表明MPTMS成功地引入到有序介孔材料上,HS-ZCS仍保持了类似于传统SBA-15高度有序的二维六方相介孔结构。对罗丹明6G的吸附实验表明,这种功能化短孔道介孔材料表现出比传统的长孔道SBA-15有更好的传输能力。

| Abstract: | Sulfhydryl-functionalized HS-Zr-Ce-SBA-15(HS-ZCS) mesoporous materials with unique hexagonal platelet morphologies and short channels were synthesized by a co-condensation method using 3-mercaptopropyltriethoxysilane(MPTS) as organic modifiers,tetraethyl orthosilicate(TEOS) as a silica source,zirconyl chloride and cerous nitrate as precursors,and pluronic P123 triblock copolymer as a structure directing agent.The as-synthesized materials were characterized by low-angle X-ray diffraction(LXRD),transmission e... |
