Greenhouse Gas Sensing Properties of ZnO Nanorods

ORAL

Abstract

We report on the sensing properties of electrochemically deposited zinc oxide (ZnO) nanorod films. The interaction between methane and the ZnO nanorods causes a drop in the resistivity depending on the methane concentration. We will present our first results for ZnO nanorods grown on different substrates and operated between 150 $^{\circ}$C and 300 $^{\circ}$C. Our first measurement indicate a sensitivity for methan of better than 0.1{\%}. The ZnO nanosensor characterization was carried out by using bulk X-ray diffraction (XRD) and by scanning electron microscopy (SEM).
