郑欣梅，齐彦兴，张小明，索继栓将手性Salen Mn(III) 配体固载到SBA-15上来催化苯乙烯的不对称 环氧化反应 ，结果表明SBA-15为载体的催化剂可以得到与 均相催化剂 同样甚至更好的催化效果。

2020年1月1日 · The morphology of SBA-15 and SBA-16 was assayed by a scanning electron microscopy (SEM, JEOL 35CF) with an acceleration potential of 10 kV. The samples were dried under air flow on a porthole and posteriorly were metalized with gold coating (thickness of 245 Å) (PELCO 91,000 sputter coater).

2016年11月8日 · Mesoporous SBA-15 has shown great advantages as catalyst support for large molecules because of their large surface area, tunable pore diameter (4–30 nm) and thick pore walls. SBA-15 materials are prepared by using non ionic triblock copolymer P123 (EO 20 PO 70 EO 20) as surface directing agent in acidic media. The textural and morphological ...

2011年9月16日 · Several techniques, such as element analysis, nitrogen sorption analysis, small angle X-ray diffraction, scanning electron microscopy (SEM), FTIR, solid-state 29 Si and 13 C NMR spectroscopy are employed to characterize the SBA-15 materials before and after surface modification with the organic components. Nitrogen sorption analysis is ...

通过粉末X射线衍射（XRD）、扫描电子显微镜（SEM）、电感耦合等离子体（ICP）发射光谱、透射电子显微镜（TEM）、N{sub 2}-吸附和紫外-可见漫反射光谱。甲基橙（MO）的光降解用于研究其光催化性能。表明SBA-15的形貌对复合材料的光催化活性有很大影响。当TiO{sub 2 ...

2020年3月19日 · SBA-15 is a mesoporous silica sieve based on uniform hexagonal pores with a narrow pore size distribution and a tunable pore diameter of between 5 and 15 nm [1].

2020年2月1日 · In this project, functionalization of large-pore mesoporous SBA-15 materials was carried out by post-modification using 3-aminepropyltriethoxysilane (APTES), 3-mercaptopropyltrimethoxysilane (MPTMS), 3-chloropropyltriethoxysilane (CPTES), to give R-SBA-15 where R is the functional group on the surface (NH 2, Cl, and SH) as shown in Scheme 1.

2 天之前 · Herein, hierarchical SBA-15-based porous monoliths, with three levels of porosity (micro- and mesopores from the pores arrangement of the silica structure, and macropores from the replication of polymer beads), were prepared by simple inverse-opal technique. ... SEM micrographs of the M-SBA-1Bento hierarchical porous monolith are shown in Fig. ...

2024年11月5日 · A novel heterogeneous catalyst supported by mesoporous silica SBA-15, which can show catalytic activity in a base-free environment and can be recycled, was synthesized and tested for transfer hydroge...

疏水沸石被认为是捕获挥发性有机化合物（voc）的最有希望的吸附剂之一。在此贡献中，制备了具有不同形态的分层结构的zsm-5 / sba-15复合材料，包括血小板，六边形棱柱，长六边形棱柱和长棒。使用xrd，sem和tem-edx对所有材料进行了表征，这证实了两种沸石在复合物中的高度分散 …
