摘要
采用水热法合成ZnO一维纳米线材料,以活性炭粉与纳米ZnO复合构筑出ZnO/活性炭复合材料,探究了复合材料对乙醇气体的敏感性能。结果表明,150℃时,ZnO/活性炭复合材料传感器对乙醇气体具有良好的响应-恢复特性;对于浓度5×10^(-6)的乙醇,传感器灵敏度可达到4.75;传感器灵敏度随着乙醇浓度增加呈正相关提升,且具有很好的重现性。
ZnO narowires were synthesized by adopting hydrothermal synthesis,and ZnO/activated carbon composite material was then prepared by compounding activated carbon powder and nano⁃ZnO.The research on the sensing performance of such composite to ethanol gas shows that the sensor with ZnO/activated carbon composite presents good response and recovery characteristics to ethanol gas at 150℃.Its sensitivity to the ethanol with concentration of 5×10^(-6) can be up to 4.75,and will increase positively with the increase of ethanol concentration,which presents a reproducibility and stability.
