摘要
The results concerning the gas-sensing characteristics of novel NO2 gas sensors, fabricated from complex [Cr(bipyO(2)) Cl-2]Cl thin films, were first presented. The sensors exhibited high response to NO2 gas in the concentration range from 1.97% to 6.67% at relative low temperatures (from room temperature to 348 K). No response to H2S and SO2 was observed. The maximum response for 6.03% NO2 was approximately 11.7 at 338 K and 10 V operating voltage. The response time of the sensors was about 4.5 min for NO2 and the recovery time about 40 s. The effect of the electrical resistance change of the sensors in the presence of NO2 could be used for gas sensing measurements. The performance and reliability of the sensors showed their potential applications for monitoring and controlling NO2 component continuously in chemical production.
