A ZnO Gas Sensor with an Abnormal Response to Hydrogen
نویسندگان
چکیده
ZnO is a commonly used material for hydrogen gas sensors. In this study, nanofiber film with diameter of approximately 60 nm was synthesized by the electrospinning method. Compared to previously reported sensors, an abnormal phenomenon observed here, where resistance increased upon exposure in temperature range from 210 °C 330 °C. The physical mechanism explored through microstructure analysis and DFT simulation calculations that showed total charge transfer 0.65 e molecule. This study can push forward understanding sensing.

متن کاملA ZnO Nanorod Based Layered ZnO/64° YX LiNbO3 SAW Hydrogen Gas Sensor
A zinc oxide (ZnO) nanorod based surface acoustic wave (SAW) sensor has been developed and investigated towards hydrogen (H2) gas. The ZnO nanorods were deposited onto a layered ZnO/64° YX LiNbO3 substrate using a liquid solution method. Micro-characterization results revealed that the diameters of ZnO nanorods are around 100 and 40 nm on LiNbO3 and Au (metallization for electrodes), respective...
متن کاملAn ultra-sensitive hydrogen gas sensor using reduced graphene oxide-loaded ZnO nanofibers.
We developed a hydrogen sensor of reduced graphene oxide-loaded ZnO nanofibers. An extremely high response of about 866 at a low concentration of 100 ppb was obtained. The combined effect of the presence of rGO nanosheets and hydrogen-induced metallization of ZnO played a crucial role in enhancing the detection behavior.
متن کاملZnO Nanowires/Nanobelts Structured CO Gas Sensor
Zinc oxide nanowires/nanobelts thin films were prepared by thermal evaporation deposition of Zn on two different kinds of substrates, namely Cr-glass and Cr-<100> n-type Si. ZnO nanostructured based COgas sensing thin films were formed, and the morphologies of these films were investigated by scanning electron microscopy (SEM). The sensing response of the films toward CO gas at operating temper...

The high crystallinity ZnO nanoparticles with an average particle diameter 30 nm have been successfully synthesized with a surfactant-mediated method. The cationic surfactant (cetyltrimethylammonium bromide, CTAB) and the hydrous metal chlorides (ZnCl2⋅2H2O) appear to be the good candidates for obtaining a high yield of nanoparticles. The structural and morphological characterizations were carr...
