Reduced graphene oxide (rGO)-titanium dioxide (TiO2) hybrid material has been prepared through a facile hydrothermal method for ammonia detection at room temperature. The combined characterizations including X-ray diffraction (XRD), ultraviolet-visible spectroscopy (UV–vis) and scanning electron microscopy (SEM) indicated the successful formation of rGO-TiO2hybrid. It also showed that the morphology of graphene sheets was greatly improved to become porous and undulating due to introduction of synthetic titanium dioxide. Accordingly, the hybrid-based sensor showed much more excellent sensing properties in comparison to that of bare graphene film sensor. The mechanism for the improvement could be ascribed to the synergetic effect between rGO sheets and TiO2nanospheres, specifically, the enrichment of active adsorption sites on account of the supporting function of TiO2nanospheres.
