Construction of 2D/2D Heterogeneous of ZIF‐8/SnS2 Composite as a Transfer of Band‐Band System for Efficient Visible Photocatalytic Activity

Abstract 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.
