Realizing low-temperature detection of NO2 is crucial to protecting the environment and human health. In this study, SnS2/SnO2 hexagonal nanosheets with an average size 630 nm were synthesized by a two-step process. Subsequently, Ag nanoparticles modified on surface form Ag-modified nanoheterojunctions. Compared SnS2 sensors, Ag/SnS2/SnO2-based sensors have better gas-sensing performance at optimum operating temperature 100 °C, including higher response, stability, excellent selectivity NO2. The response value Ag/SnS2/SnO2 sensor 7 ppm °C 56.4, which four times than that sensor. outstanding sensing properties can be due combination modification formation SnS2–SnO2 heterojunction.
