Özet
In this study, ethanol detection performance of divanadium pentoxide (V2O5) nanowire array was investigated at various temperatures. The main purpose of this study is to develop a novel V2O5 nanowires-based sensor for the detection of ethanol using an Anodic Aluminum Oxide (AAO) template by direct voltage electrodeposition at room temperature. It was observed that the V2O5 nanowires were approximately 60 nm in diameter in a large area of 6 cm2 . X-ray Diffraction (XRD) spectrum indicated the formation of V2O5. The XRD peak was indexed as V2O5 located at 2h% 20 that is attributed to the (001) lattice plane. The sensitivity of the V2O5 nanowire array was found 0.24 at 200 C for 50 ppm ethanol. The results reveal that the diffusivity of the V2O5 molecules increases rapidly with increasing temperature, causing an increased sensitivity. The maximum sensor response was obtained at 200 C. The limit of detection (LOD) of the V2O5 nanowire array sensor was 500 ppb at 200 C. The response time (t90) of the V2O5 nanowire array sensor was calculated to be 52 s and the recovery time was 26 s at 200 C.
