Ethylamine has been widely used in production and life, but it needs to be monitored in real-time because of its important harm to human health. In this study, an SnO 2 /rGO nanocomposite gas sensitive material was synthesized by hydrothermal method, and the gas-sensing properties of ethylamine were tested by a self-made gas sensitivity test platform. The results show that the SnO2/rGO nanocomposite materials have good gas-sensitive performance of ethylamine and low detection limit (up to 1 ppm). Finally, the mechanism of gas sensitivity is proposed.
