Abstract
In this work Graphene Oxide (GO) and SnO2 nanowires (NWs) composite sensing performance were studied. Single crystal SnO2 NWs were directly grown by thermal evaporation method and GO was successfully synthesized using modified Hummers method. RF magnetron sputtered Pt particles were used as a catalyst for the growth of SnO2 NWs. Drop cast technique was used to deposited GO on top of the SnO2 NWs. FE-SEM (LEO 1525) was used to investigate the morphology of SnO2 NWs and GO. Fabricated sensors were tested towards various concentration of H2 at different working temperatures. This GO/SnO2 hybrid sensors show a reversible response to H2 at low operating temperature.
