The material formed by combining two kinds of materials in a certain way is called composited material. Although reduced graphene oxide (rGO) has extremely high electron mobility, good chemical stability and high specific surface area, rGO sensors have problems such as slow recovery kinetics and poor selectivity. Tin disulfide (SnS2)as a two-dimensional metal chalcogenide in the middle gap has excellent gas sensitivity and recovery kinetics, but the resistance is too large when working at room temperature. Therefore, the combination of SnS2 and rGO can have both high electron mobility and excellent gas sensitivity. Therefore, the research of gas sensors based on SnS2/rGO has also become a hot spot. This article reviews the research progress of SnSn/rGO in the field of gas sensors.
