The green synthesis of gas‐sensing materials, which monitor volatile organic compounds, avoid synthesis‐induced pollution, and thus is a major challenge faced by scientific researchers. Herein, we report a microwave‐assisted green synthesis of Ag‐decorated SnO 2 nanorods with water being used as solvent and comparatively non‐toxic chemicals being used as reactant. The as‐prepared product was characterised by X‐ray diffraction, scanning electron microscopy and transmission electron microscopy. The results showed one‐dimensional Ag‐decorated SnO 2 nanorods constituted of tetragonal rutile phase of SnO 2 and cubic phase of Ag were successfully prepared. Ethanol was used as a model system for measuring gas‐sensing properties and an enhanced gas‐sensing property was found due to Ag decoration. Moreover, a linear dependence of the sensitivity on the ethanol concentration was observed.
