α-Fe2O3nanotubes was successfully prepared by single nozzle electrospinning method.Scanning electron microscope(SEM)was used to characterize the morphology of-Fe2O3nanotubes.The gas sensing properties of-Fe2O3nanotubes were investigated in detail.The results exhibit relatively good sensing properties to acetone at 240°C.The response and recovery times are about 3 and 5 s,respectively.The structure of nanotubes is beneficial to the gas sensing properties,which will enlarge the surface-to-volume ratio of α-Fe2O3and then be available for the transfer of gas,and thus improved the sensor performance consequentially.
