Abstract Graphene based hetero-nanostructured sensor systems have gained much attention for improving sensing behavior towards harmful gases, especially $NO_{2}.$ In this report, enhanced room temperature sensing response towards $NO_{2}$ gas using $rGO@Zn_{2}SnO_{4}$ nanocubes. A facile two step synthesis method is adopted involving hydrothermal synthesis for the preparation of highly monodispersed zinc stannate $(Zn_{2}SnO_{4})$ nanocubes having clear edges and length of 80 ± 0.5 nm were found to be anchored on the exfoliated rGO nanosheet supports. X-ray diffraction (XRD) studies divulge the clear existence of crystalline rhombohedral $Zn_{2}SnO_{4}$ and rGO sheets. Gas sensing studies revealed that the $Zn_{2}SnO_{4}$ nanocubes supported on rGO can detect $NO_{2}$ even at 30°C and showed enhanced sensing response compared to pristine $Zn_{2}SnO_{4}$ nanocubes based on the spill-over effect and unwrapped rGO sheets.
