Although there are a significant number of reports on zeolite synthesis, their nucleation and growth mechanisms are still under discussion. Therefore, in this work, we present an in-depth study of the effect of mother liquor addition on the synthesis of the zeolitic lamellar precursor (P)MCM-22. We analyzed several ex situ samples obtained in the presence and absence of mother liquor by X-ray diffraction, small-angle X-ray scattering, microscopy, thermogravimetry and nitrogen adsorption/desorption. We found that the spherical amorphous nanoparticles in the mother liquor were responsible for accelerating the reaction. In addition, the first crystalline sample obtained in the presence of mother liquor exhibited a high total pore volume. These new data not only helped elucidate the mechanism but also contributed to the synthesis of a material with attractive properties.

尽管有大量关于沸石合成的报道，但它们的成核和生长机理仍在讨论中。因此，在这项工作中，我们提供了对母液添加对沸石层状前体（P）MCM-22合成的影响的深入研究。我们分析了几种非原生境在存在和不存在母液的条件下，通过X射线衍射，小角X射线散射，显微镜，热重分析和氮吸附/解吸获得的样品。我们发现母液中的球形无定形纳米颗粒负责加速反应。另外，在母液存在下获得的第一结晶样品表现出高的总孔体积。这些新数据不仅有助于阐明机理，而且还有助于合成具有诱人特性的材料。
