摘　　要：Synthetic graphene composite was modified on a transducer of quartz crystal microbalance（QCM） tofabricate a gas sensor for low concentration nitrogen dioxide（NO2） detection. The gas sensing properties of the QCMcoated with SnO2-rGO and AgNPs-SnO2-rGO composites were investigated when exposing QCM to low NO2 con-centration（2.05--20.5 mg/m3） atmosphere at room temperature. The sensing performances of ,he QCM withAgNPs-SnO2-rGO composites were enhanced by the introduction of Ag nanoparticles, and the QCM modified withAgNPs-SnO2-rGO composites could detect NO2 at room temperature.
