Room Temperature Acetone Sensing Based on ZnO Nanowire/Graphene Nanocomposite

In this paper we report the preparation of a hybrid material by combination of graphene and ZnO nanowire for acetone sensing applications. The ZnO thin films and ZnO NWs were prepared by sol-gel and hydrothermal methods, respectively. The morphological analyses of the obtained material have been performed by means of scanning electron microscopy. These sensors exhibited an enhanced response to acetone concentration as low as 100 ppm at room temperature. The gas sensing analysis of the hybrid material showed that the structure can be used for fabrication of practical sensors
