Two‐dimensional (2D) mesoporous heterostructures combining ultrathin nanosheet morphology, periodic porous surface structures, and diverse hybrid compositions have become increasingly important for renewable energy storage and electronics. However, it remains a great challenge to develop a universal method to prepare 2D mesoporous heterostructures. Herein, we report a composite‐micelle‐directed interfacial assembly method to synthesize heterostructures of an ultrathin 2D material covered with mesoporous monolayers assembled on both sides. To demonstrate the concept, we first fabricated a new sandwichlike carbon@MXene@carbon mesoporous heterostructure through the self‐assembly of exfoliated MXene nanosheets and block copolymer F127/melamine‐formaldehyde resin composite micelles and subsequent thermal treatment. Finally, we demonstrate that the carbon@MXene@carbon mesoporous heterostructured nanosheets manifest remarkably enhanced electrochemical performance as a cathode material for lithium–sulfur batteries.

由Micelle指导的界面组装可普遍访问二维介孔异质结构。

二维（2D）介孔异质结构结合了超薄纳米片的形态，周期性的多孔表面结构以及多样的混合成分，对于可再生能源存储和电子学来说变得越来越重要。然而，开发通用的制备二维介孔异质结构的方法仍然是一个巨大的挑战。本文中，我们报道了一种复合胶束定向界面组装方法，该方法可合成覆盖有在两侧组装的中孔单层膜的超薄二维材料的异质结构。为了证明这一概念，我们首先通过剥离的MXene纳米片和嵌段共聚物F127 /三聚氰胺-甲醛树脂复合胶束的自组装和随后的热处理，制造了一种新的三明治状carbon @ MXene @ carbon介孔异质结构。最后，
