Constructing two‐dimensional (2D) heterostructured nanocomposites is an effective method to boost photo‐generated carrier separation efficiently using layer material. In this work, a tightly coupled 2D/2D ZIF‐8/SnS 2 nanosheet heterogeneous composite was successfully prepared. Due to the good heterogeneous interface between 2D SnS 2 and 2D ZIF‐8 nanosheet, 2D/2D ZIF‐8/SnS 2 nanocomposites formed a large contact interface, leading to high efficient interfacial charge transfer efficiency and shortening the distance of charge transmission. As a result, the optimized SnS 2 /2D‐ZIF‐8 composites possess excellent photocatalytic properties and the rate of degradation toward MB under visible light for 100 minutes is 2.32 and 26.75 times than that of pure SnS 2 and 2D‐ZIF‐8, respectively. This work offers an efficient way to design 2D/2D heterojunction composites as visible‐light‐driven catalyst for the photocatalytic application.
