Abstract: This invention provides a highly-selective and sensitive Nitrogen oxide gas sensor based on the resistive transducing platforms using two-dimensional (2D) tin disulphide (SnS2) flakes that can operate below 150° C. This sensor operates based on the physisorption of nitrogen oxide on the surface of the sensitive layer. The fabrication of the sensors is low-cost. The tin disulphide is preferably produced by reacting tin dichloride at elevated temperature with powdered sulphur in a liquid phase to form tin disulphide nano particles and separating the tin disulphide nano particles from the liquid phase.
