| 摘要: 以气溶胶辅助自组装的方法合成了超疏水性的有机无机杂化层状钛硅微球材料（micro sphere layered organo-titanosilicate，ms-LOTS）；利用扫描电子显微镜（SEM）观察材料的微球形貌，利用X射线粉末衍射（XRD）和红外光谱（FT-IR）表征材料的结构信息，并考察其在环己烯环氧化反应中的催化活性。研究发现，前驱体浓度和自组装温度是影响材料的微球形貌的关键因素，控制一定的合成条件，可以制备颗粒分布均匀、粒径为2~4 μm的超疏水性层状钛硅微球材料；该材料在室温下环己烯环氧化反应中表现出良好的催化活性。 | |

| Abstract: Layered organo-titanosilicate materials with a micro sphere morphology (denoted as ms-LOTS) were synthesized via the aerosol-assisted self-assembly (AASA) method. The morphology and materials' structure of ms-LOTS was characterized by SEM, XRD and FT-IR. The temperature and concentration play an important role in catalytic activity. The ms-LOTS with a uniform sphere size of 2~4 μm were successfully prepared by the optimization of synthetic condition (350℃ and low concentration). At room temperature, ms-LOTS show improved catalytic performance in the epoxidation of cyclohexene. | |
