This work demonstrates the fabrication of a highly selective ammonia (NH3) gas sensor based on Graphene/SilvereSilver Oxide/Polypyyrole (Gr/AgeAg2O/PPy) nanocomposite. To archive this objective, a cost-effective, room temperature mediated solution-based synthesis of Gr/AgeAg2O/PPy nanocomposite was exploited as an efficient performance NH3 gas sensor through combining the exceptional electrical characteristics of Graphene and sensing abilities of AgeAg2O/PPy. |
