Abstract

Synthetic graphene composite was modified on a transducer of quartz crystal microbalance(QCM) to fabricate a gas sensor for low concentration nitrogen dioxide(NO2) detection. The gas sensing properties of the QCM coated 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 the QCM with AgNPs-SnO2-rGO composites were enhanced by the introduction of Ag nanoparticles, and the QCM modified with AgNPs-SnO2-rGO composites could detect NO2 at room temperature.
