Facile Fabrication and Sensing Characteristics of TiO_2 Nanosheets Using Sonication

초록

This study focuses on the fabrication of TiO_2 nanosheets and their gas sensor application. A simple sonochemical method is employed to fabricate the TiO_2 nanosheets. The obtained samples were investigated by transmission electron microscope(TEM) and X-ray Diffraction(XRD). The TiO2 nanosheets were coated on substrates by a dropping method followed by heat treatment. The sensor responses to volatile organic compounds(VOCs) such as toluene, benzene, ethanol and acetaldehyde were studied. It was found that the TiO_2 nanosheets sensors are able to detect ppb-levels of VOC gases.
