Abstract Structured, porous, and hollow tubular tin oxide (SnO 2 ) and reduced graphene oxide (RGO) composites were synthesized through a combination of electrospinning and hydrothermal procedures. The morphology and structural features of the samples were analyzed and their sensing performance was tested. RGO/SnO 2 composites exhibited a better sensing performance than SnO 2 . The optimum mass ratio of RGO in the composite was assessed as 1 w%, leading to an excellent sensing response of 10.0–32.2 ppm NO 2 at a temperature of 150 °C, approximately 10-fold that of SnO 2 . Thus, the enhancement of the gas sensing properties was attributed to the addition of RGO.
