© 2015 American Chemical Society. In this work, flame-spray-made undoped SnO2nanoparticles were loaded with 0.1-5 wt % electrolytically exfoliated graphene and systematically studied for NO2sensing at low working temperatures. Characterizations by X-ray diffraction, transmission/scanning electron mi...
