dc.description.abstractCopper Oxide (Cu2O) nanowires were synthesized on a glass substrate by using anodization method and then their structural, optical, electrical and gas sensing properties were investigated. Copper thin films that coated on glass substrates with evaporation technique were anodized in 0.2 M KOH + 0.1 M NH4F solution for 5 min at room temperature. Then, the crystallization of nanowires was handled via annealing at 280 °C under vacuum. The fabricated nanowires were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and UV–vis spectrophotometer. The DC electrical measurements of Cu2O nanowires were done in the temperature range of 30 °C–200 °C under dry air. Cu2O nanowires were tested against to H2 in dry air ambient depending on concentration and temperature. It was observed that the ideal working temperature with highest sensor response was determined at 200 °C. © 2016 Elsevier B.V.
