利用两性表面活性剂十六烷基磺基甜菜碱(SB)的辅助作用实现了农药功夫菊酯(LCT)在锂皂石(LAP)中的插层。先用离子交换法将SB、十二烷基羧基甜菜碱(DCB)、十二烷基氧化胺(OA)和阳离子表面活性剂十六烷基三甲基溴化铵(CTAB)分别插层LAP,然后用SB胶束将LCT引入层间,得到LCT/SB-LAP、LCT/DCB-SBLAP、LCT/OA-SB-LAP和LCT/CTAB-SB-LAP复合材料。采用X射线衍射(XRD)、液体核磁共振(^(1)HNMR)、电感耦合等离子发射光谱(ICP-OES)、傅里叶变换红外光谱(FT-IR)、热重/差热分析(TGA/DTA)和扫描电镜(SEM)对复合材料进行了表征。结果表明,LCT/SB-LAP、LCT/DCB-SB-LAP、LCT/OA-SB-LAP和LCT/CTAB-SBLAP的层间高度分别为3.61、3.13、3.13和3.41 nm;LCT伴随SB分子成功进入LAP层间。提出了LCT在LAP中的插层机理。对复合材料中LCT释放行为的研究结果表明,释放速率和累积释放量主要依赖表面活性剂类型及其在层间的排列方式。

Zeolite nanosheets with a short b-axis thickness are highly desirable in lots of catalytic reactions due to their reduced diffusion resistance. Nevertheless, conventional synthesis methods usually require expensive structure-directing agents(SDAs), pricey raw materials, and eco-unfriendly fluorine-containing additives. Here, we contributed a cost-effective and fluoride-free synthesis method for synthesizing high-quality MFI zeolite nanosheets through a Silicalite-1(Sil-1) seed suspension and urea cooperative strategy, only with inexpensive colloidal silica as the Si source. Our approach was effective for synthesizing both Sil-1 and aluminum-containing ZSM-5 nanosheets. By optimizing key synthesis parameters,including seed aging time, seed quantity, and urea concentration, we achieved precise control over the crystal face aspect ratio and b-axis thickness. We also revealed a non-classical oriented nanosheet growth mechanism, where Sil-1 seeds induced the formation of quasi-ordered precursor particles, and the(010)crystal planes of these particles facilitated urea adsorption, thereby promoting c-axis-oriented *** obtained ZSM-5 nanosheets exhibited exceptional catalytic performance in the benzene alkylation with ethanol, maintaining stability for over 500 h, which is 5 times longer than traditional ZSM-5 catalysts. Furthermore, large-scale production of ZSM-5 nanosheets was successfully carried out in a 3 L highpressure autoclave, yielding samples consistent with those from laboratory-scale synthesis. This work marks a significant step forward in the sustainable and efficient production of MFI nanosheets using inexpensive and environmentally friendly raw materials, offering the broad applicability in catalysis.
