Development of sustainable routes for synthesis of zeolites is very important because of wide applications of zeolites at large scale in the fields of catalysis, adsorption, and separation. Here we report a novel and generalized route for synthesis of zeolites in the presence of NH4F from grinding the anhydrous starting solid materials and heating at 140-240 °C. Accordingly, zeolites of MFI, BEA*, EUO, and TON structures have been successfully synthesized. The presence of F(-) drives the crystallization of these zeolites from amorphous phase. Compared with conventional hydrothermal synthesis, the synthesis in this work not only simplifies the synthesis process but also significantly enhances the zeolite yields. These features should be potentially of great importance for industrial production of zeolites at large scale in the future.
开发沸石的可持续合成路线非常重要，因为沸石在催化、吸附和分离等领域的大规模应用。在这里，我们报告了一种在 NH4F 存在下通过研磨无水起始固体材料并在 140-240°C 下加热来合成沸石的新的通用路线。相应地，成功合成了 MFI、BEA*、EUO 和 TON 结构的沸石。F(-)的存在驱动了这些沸石从无定形相的结晶。与传统的水热合成相比，这项工作中的合成不仅简化了合成过程，而且显著提高了沸石的产率。这些特点对于未来沸石的大规模工业化生产具有重要意义。
