| Abstract: | To study and prepare the material possessing low detection level,fast response and high sensitivity to NOx at room temperature,SnO2/C is synthesized by electrospunning method.The characteristics and morphology of the material are studied by SEM,TEM,XRD.The results show that the surface of the material possesses a wealth of microporous,mesoporous and macroporous,and the majority of the mesoporous is about 10 nm.At room temperature(16~18 ℃),NOx gas sensor test reveals that the composite material which is composed of PS/SnCl2 nanofibers has better sensitivity of NOx than pure SnO2 after calcinations.The volume fraction of the lowest detection is 0.97×10-7,and after 48 h,the reproducibility is also better.The mechanism of gas sensor indicates that O2 in air is adsorbed on the surface of SnO2/C composite,then O-is formecl.It causes that the sensitivity of SnO2/C is improved. |
