A highly sensitive room-temperature sensing material for NH3: SnO2-nanorods coupled by rGO

SnO2-nanorods coupled by reduced graphene oxide (rGO) nanostructures were synthesized through a hydrothermal method, and their NH3 sensing properties were studied. The uniform SnO2 nanorods randomly grew on the reduced graphene oxide (rGO) substrate and formed a network structure. The microstructure and morphology of the as-prepared materials were characterized by various techniques. A gas sensor fabricated from the as-prepared SnO2-nanorods...
