A simple one-step synthesis method is demonstrated, enabling the thickness of assembled silicalite nanosheets to be tuned from 2 to 30 nm. The adjustement is achieved by mixing two common organic structure-directing agents (OSDAs): tetrapropylammonium (TPA) and tetrabutylammonium (TBA). During the hydrothermal synthesis, there is a preferential uptake of TPA, and the proportion of incorporated TBA can be deduced accordingly. The proportion of TBA, known to favour silicalite nanosheets, determines the nanosheets’ thickness and the morphological variations observed.

组装的五元硅纳米片沸石：通过简单直接的双模板方法调整片材厚度

演示了一种简单的一步合成方法，使得组装的硅沸石纳米片的厚度可以在 2 至 30 nm 之间调节。这种调节是通过混合两种常见的有机结构导向剂（OSDA）来实现的：四丙基铵（TPA）和四丁基铵（TBA）。在水热合成过程中，TPA优先被吸收，因此可以相应地推导出TBA的掺入比例。 TBA 的比例（已知有利于硅沸石纳米片）决定了纳米片的厚度和观察到的形态变化。
