An efficient chemical way to finely control the layer-by-layer stacking of inorganic nanosheets (NS) is developed by tuning the type and composition of intercalant ion, and the reaction temperature for restacking process. The finely controlled stacking of NS relies on a kinetic control of the self-assembly of NS in the presence of coordinating organic cations. A critical role of organic cations in this assembly highlights the importance of the appropriate activation energy. Of prime importance is that a fine-control of the interstratification of 2D NS is highly effective not only in tailoring its pore structure but also in enhancing its electrode activity. The present study clearly demonstrates that the kinetically controlled restacking of NS provides a facile and powerful method to tailor their stacking number and functionality.
通过调节插层离子的类型和组成以及重新堆叠过程的反应温度，开发了一种有效控制无机纳米片（NS）逐层堆叠的化学方法。NS 的精细堆叠依赖于在配位有机阳离子存在下 NS 自组装的动力学控制。有机阳离子在该组装中的关键作用突出了适当活化能的重要性。最重要的是，二维 NS 层间的精细控制不仅可以有效地调整其孔结构，而且可以提高其电极活性。本研究清楚地表明，NS 的动力学控制重新堆叠提供了一种简单而强大的方法来调整它们的堆叠数和功能。
