Abstract

We report the nanostructures and gas-sensing properties of Zinc oxide nanosheets prepared by hydrothermal method. In particular, needle-like Zinc oxide was also prepared for comparison. The morphology and structural properties were investigated using X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM). Subsequent gas-sensing measurement between Zinc oxide nanosheets and Zinc oxide nanoaciculars indicated that the nanosheets exhibited higher gas response to ethanol. The enhanced gas sensing properties of Zinc oxide nanosheets suggests that governing the shape and the surface structure of nano Zinc oxide is a significant approach for developing high performance gas sensors.
