Abstract:
In this research we have developed an easy way to synthesize hybrid three-dimensional reduced graphene oxide/ copper oxide structures. The micro/nano structures of copper oxide were formed on the three-dimensional configuration of graphene-sheets during the hydrothermal synthesis. These structures were then characterized for gas sensing application. On account of copper oxide affinity toward adsorption of hydrogen sulfide molecules, electrical properties of the structure are studied in the presence of this environmentally hazardous gas. Accordingly, the structure has shown improved response to H2S gas molecules, regarding a thermal treatment at 200℃, as a result of charge transfer to the structure. The samples were completely recovered to the baseline through heating at 150℃ for 5 minutes
