摘要：The efficient, environmentally friendly, and cost-effective synthesis of zeolites holds significant importance in both academic and industrial applications. Traditionally, the synthesis of pure silicon MFI zeolite (Silicalite-1) through hydrothermal methods employing non-organic amine systems posed substantial challenges due to weak directing abilities and competitive growth of impure phases. In this study, Silicalite-1 zeolite was successfully synthesized in a methanol system, and particular attention was paid to the role of methanol and the crystallization conditions (water-to-silica ratio, alcohol-to-silica ratio, etc.) during the hydrothermal synthesis process. Computational and characterization techniques such as Monte Carlo simulations, XRD, SEM, TG, N2 adsorption-desorption, and NH3-TPD were employed. The results indicated that the introduction of seed crystals significantly improved the initial nucleation difficulties in the methanol system; a pure phase of Silicalite-1 with high crystallinity was directly synthesized when the seed crystal input was 3% and the alcohol-to-silica ratio was 3.3, showing excellent catalytic activity in the MTP reaction. Lastly, the low-cost synthesis strategy for Silicalite-1 proposed in this paper has notable research value and industrial application prospects. ? 2025 Chemical Industry Press Co., Ltd..
