摘要：

A simple method to synthesize graphene-zinc oxide nanocomposite has been developed. A reduced graphene oxide-ZnO nanocomposite was prepared using a reflux method with ethylene glycol as medium. X-ray diffraction analysis, scanning electron microscopy, energy-dispersive spectrometry, and nitrogen adsorption-desorption measurements were used to characterize the resulting composite materials. The highest response of about 98% was observed when using pure ZnO at 300A degrees C, while the second highest sensor response of about 96% was achieved by graphene-ZnO with 1:3 composition. It was found that the graphene-zinc oxide hybrid has potential to improve sensor performance at low temperature. The graphene-ZnO hybrid with 1:3 composition showed good response of 36% at 125A degrees C, an operating temperature at which pure ZnO showed no response.
