摘要：

In this work, the influence of Cu and Ni doping on the propane gas (C3H8) detection of zinc oxide (ZnO) samples was evaluated. Three powder samples: (a) pure ZnO, (b) Ni-doped ZnO, and (c) Cu-doped ZnO, were obtained by homogenous precipitation method. The Ni and Cu concentration was of 1 at.%. The X-ray diffractograms indicate that all samples showed a hexagonal wurtzite-type crystal structure. Micrographs obtained by scanning electron microscopy (SEM) show a spherical surface morphology typical of nanostructured materials in the pure ZnO and ZnO/Ni samples. The gas sensing devices were manufactured by pressing the powders in pellets form. The sensing response of all pellets was measured by the surface electrical resistance change in a propane (C3H8) atmosphere at concentrations from 0 to 500 ppm at different operation temperatures (100, 200, and 300 degrees C). ZnO/Cu pellet presented the highest resistance change, registered at 300 degrees C in a propane concentration of 500 ppm.
