Abstract

Silver-decorated tin oxide/reduced graphene oxide (Ag/SnO2/rGO) composite was synthesized by a facile and cost-effective hydrothermal method for enhancing gas-sensing performance toward ethanol. The morphology and structure of the Ag/SnO2/rGO composite was characterized by X-ray powder diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive spectrum (EDS), transmission electron microscopy (TEM) and Brunauere-Emmette-Teller (BET). The XRD and EDS studies demonstrated that Ag nanoparticles were present in the Ag/SnO2/rGO composite. The SEM and TEM studies indicated that the rutile SnO2 nanoparticles were well distributed on reduced graphene oxide sheets. According to the BET results, Ag/SnO2/rGO composite had a high specific surface area of 191.583 m2/g. In addition, the sensor based on Ag/SnO2/rGO exhibited perfect sensing performance toward ethanol than the sensors based on the SnO2 and SnO2/rGO owing to its 3D porous nanostructure, p–n heterojunctions and Ag decoration. The gas-sensing results indicated that the sensor with 2 wt% silver concentration exhibited good gas-sensing properties, and the sensitivity of the sensor to 400 ppm ethanol was 95.3 at the optimum operating temperature (280 °C), which almost doubled that of the SnO2/rGO sensor (55.3).
