MoO3-NiO composites were prepared by a simple one-step electrospinning method and were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and nitrogen adsorption-desorption test. Humidity sensing properties of MoO3-NiO composites with different mass ratios were studied, the best result was obtained for the sample with MoO3-NiO mass ratio of 0.5 (S1) under the same preparation condition. The impedance of the sensor changed more than three orders of magnitude when relative humidity ranged from 11% to 95%. The response and recovery time were about 2 s and 10 s respectively with maximum hysteresis of <2%RH (relative humidity). The above findings suggest potential applications of the MoO3-NiO composite (S1) in high performance humidity sensors.
