Abstract:: In order to solve the problem that the nano-TiO2 sensor had a fast response to H2,but the recovery was too slow at room temperature,commercial nano-In2O3 was introduced to modify it.In2O3/TiO2 nanocomposite pressed films and In2O3/TiO2 nanotube arrays were prepared by pressing method and anodic oxidation-deposition method,respectively.They were applied to hydrogen sensors,and their hydrogen sensitivity were studied at room temperature.The samples were characterized by scanning electron microscopy,X-ray diffraction and specific surface area measurement.And the effects of different electrodes (Ag,Pt,Pd),different heat treatment temperatures and different In2O3/TiO2 mass fractions on the hydrogen sensitivity of the sensors at room temperature were studied.It was found that compared with the pure TiO2 sensor,the composite sensor expanded the detection range of hydrogen,and could detect 1×10-6-1×10-3 hydrogen at room temperature,and the recovery time was greatly shortened.Among them,the In2O3/TiO2 composite sensor with a mass fraction of 20% and annealed at 600 ℃ with Pt as the electrode exhibited the best hydrogen sensitivity.At room temperature,the response time to 1×10-6 H2 was 7 s,and the recovery time is 32 s.
