Hexagonal Prism ZnO Nanosheets: Synthesis and Application for High-sensitive Gas Sensor
Hexagonal prism zinc oxide (ZnO) nanosheets have been successfully synthesized via a facile hydrothermal route without any surfactant combined a post-annealing process.Moderate ethanol, as reaction solvent, affected the type of architectural formation of ZnO.The product with hexagonal wurtzite structure was characterized by X-ray diffraction (XRD), the morphology and structure was observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM).It found that the hexagonal prism zinc oxide (ZnO) nanosheets with a diameter of about 150-300nmwere uniform and mono-disperse.Gas-sensing properties made clear that the ZnO hexagonal prism gas sensors exhibited a high reversible, fast response and short recovery time, good selectivity, excellent repeatability and stability at 320℃.The investigations demonstrate that the hexagonal prism ZnO architecture is an ideal candidate for fabricating highly sensitive gas sensors.
