The synthesis of Cu2O of nanowires on glass substrate was investigated for usage as a H-2 sensor device. The amorphous copper oxide nanowires were synthesized on glass substrate via thin film anodization in 0,2M KOH + 0,1M NH4F solution. The nanowires were crystallized with annealing the samples at 280 C under vacuum conditions. The structural changes of nanowires were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The DC electrical measurements of Cu2O nanowires were carried out in the temperature range of 303-473 K under 200 sccm dry air flow. The H-2 sensing properties of as-synthesized sample after anodization and vacuum annealed sample were compared at 200 degrees C under dry air flow. The Cu2O nanowires showed better sensor response than as -synthesized sample. (C) 2015 The Authors. Published by Elsevier Ltd.
