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. Graphical abstract
