摘　　要：通过将SO32-,SCN-引入体系来提高纳米金在烟草花叶病毒(TMV)模板上的生长密度,同时将制得的TMV-纳米金复合材料以悬浮液的形式加入肯塔基参比卷烟的滤嘴中,对样品卷烟进行CO释放量的检测,并用透射电镜、紫外-可见吸收光谱、热重仪对TMV-纳米金复合材料进行分析表征。结果表明:①在添加量为0.7 mL/支的情况下,卷烟烟气CO释放量的降低率为27.43%,CO的选择性降低率为16.33%。②本方法可对纳米金进行有效的粒径控制和更为高效的负载,这也是TMV-纳米金复合材料提高卷烟烟气中CO催化氧化性能的原因所在。TMV-纳米金复合材料加入卷烟滤嘴中,可以有效地选择性降低烟气中的有害成分。SO32- and SCN- were introduced into a system to improve the growth density of nano Au on tobacco mosaic virus （TMV） template. The suspension solution of the obtained composite was added into the filter of Kentucky reference cigarette to investigate its influence on CO in cigarette smoke. Transmission electron microscope,UV-visible absorption spectrometer and thermogravimetric analyzer were utilized to characterize the composite. The results showed that： 1） at the application rate of 0.7 mL per cigarette,the reduction rate of CO delivery and selective removal rate of CO in cigarette smoke were 27.43% and 16.33%,respectively;2） the size of nano Au could be validly controlled and loading of nano Au could be more efficiently, which explained why the catalytic oxidization of CO in cigarette smoke was promoted.
