摘      要：With the development of environmental monitoring,it is urgent to establish NO_(2)sensor with good sensing *** with the traditional NO_(2)sensors made of metal oxides,NO_(2)sensors made of n-p heterostructure nanocomposites have good sensing performance in detection limit and operating *** nanoflake arrays with polyaniline film grown on the surface were prepared on ceramic tubes by hydrothermal and vapor diffusion *** gas-phase diffusion method can control the heterostructure by adjusting the diffusion *** room temperature(25℃),the construction of rich n-p heterogeneous interface enables the sensor prepared by the nanocomposite to respond to NO_(2),showing the sensing performance with the response value of 28.00 to10.00×10^(-6)NO_(2);the detection limit improved to0.01×10^(-6)and the recovery time of 18 *** this work,the sensing mechanism of NO_(2)at heterogeneous interface is analyzed,which provides a promising material for the detection of low concentration NO_(2)at room temperature.
