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/SnS2 nanosheet heterogeneous composite was successfully prepared. Due to the good heterogeneous interface between 2D SnS2 and 2D ZIF‐8 nanosheet, 2D/2D ZIF‐8/SnS2 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 SnS2/2D‐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 SnS2 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.

Synthesis and Applications of Nanostructured Hollow Transition Metal Chalcogenides

“…Semiconductor TMC is considered as a photocatalyst with potential for development due to its narrow band gap and strong absorption capacity for visible light. [70] The combination of electrocatalytic CO 2 reduction and renewable energy sources (such as sunlight and wind energy) for fuel and chemical production provides an ideal idea for the sustainability and safety of future energy. [71][72][73] Although electrocatalytic CO 2 reduction is feasible from a thermodynamic point of view, the kinetics of the reaction is slow because the CO 2 molecule is very stable.…”
