摘要/Abstract

摘要： 利用浸渍法将TS-1导向剂高度分散在介孔材料MCM-41和SBA-15的表面,制备出一系列在氧化反应中具有高活性的催化材料.对样品的表征显示催化剂保持了介孔的结构,同时具有四配位的钛物种均匀地分散于介孔催化剂的表面.催化结果显示,与钛硅分子筛(TS-1)相比,所制备的催化剂在小分子的氧化反应中表现出相似的活性,在大分子的氧化反应中展示了很高的活性,体现了介孔材料的优越性.

Abstract: TS-1 precursors were loaded and highly dispersed on the surface of mesoporous materials MCM-41 and SBA-15,and these samples are characterized by IR,UV-Vis spectra and other techniques. These results suggest that the samples retain the mesopores channels and characteristic structure of microporous TS-1. The catalytic results show that these materials are more active than conventional mesoporous Ti-MCM-41 and Ti-SBA-15. In the oxidation of large molecule,these materials exhibit a good conversion compared with mesoporous materials and microporous TS-1 especially.
