Abstract
Abstract Effectively monitoring of hazardous gases has become increasingly important for ecological environment and human health. As an emerging component of two‐dimensional materials, layered metal dichalcogenides are gaining significant attention due to their unique physical and chemical properties, thus catering well to the gas sensing application. Particularly, tin disulfide (SnS 2 ) has been widely examined recently owing to its low‐cost, earth‐abundant, and environmental friendliness features, which meet the requirements of advanced sensing platforms. Herein, the booming research advancements of SnS 2 ‐based gas sensors have been presented. Firstly, the basic attributes of SnS 2 and its ability to detect various hazardous gases are introduced. Secondly, innovative approaches that have demonstrated the effectiveness of improving the room temperature sensing performance of SnS 2 are summarized. Finally, the major challenges and future opportunities of SnS 2 are also outlined. It is ultimately expected that this timely review could offer guidance for designing high‐performance gas sensing materials and further push forward their potential applications.
