Abstract

Abstract: ZnO nanorod arrays were grown in situ on ceramic tubes by a two-step solution method. Then α-Fe₂O₃ nanoparticles were loaded on the surface of ZnO nanorods via a hydrothermal method to obtain heterogeneous α-Fe₂O₃/ZnO composites. The α-Fe₂O₃/ZnO nanorods are about 30~80 nm in diameter and 1 μm in length, which are cross-arranged to form nanorod arrays. α-Fe₂O₃ nanoparticles with a diameter of about 10 nm distributed on the surface of ZnO nanorods evenly. The gas-sensing properties of the sensors based on pristine ZnO and α-Fe₂O₃/ZnO nanorod arrays were compared, and the gas-sensing mechanism was revealed. The results show that the decoration of α-Fe₂O₃ nanoparticles significantly enhances the sensitivity and selectivity of ZnO nanorod arrays sensors to ethanol at the working temperature of 370 ℃. The response of α-Fe₂O₃/ZnO sensor to 100 μL/L of ethanol is 85.4, which is 9.1 times higher than that of pure ZnO sensor (9.4) determined under the same conditions. The response time is 7 s, and the detection limit is 0.01 μL/L. The work can be applied to the rapid, high sensitivity and selectivity detection for trace ethanol.
