摘　　要：采用常压纳秒脉冲氩气冷等离子体分解二茂铁/乙醇溶液制备铁碳混合物纳米颗粒,采用扫描电镜对产物进行表征,发现影响纳米颗粒粒径的主要参数是电极间距。当电极间距较小,即利用等离子体对液体进行接触式处理时,产生的颗粒粒径较大,约10 nm;当电极间距较大,即利用等离子体余辉对液体进行非接触式处理时,产生的颗粒粒径较小,约3-5 nm。当电源频率在100-1200 Hz范围内变化时,对颗粒粒径没有明显影响。To prepare hybrid iron and carbon nanoparticles,a nanosecond pulse atmospheric argon cold plasma is used to dissociate ferrocene/ethanol solution.Scanning electron microscope is used to characterize the samples.It is found that the average size of produced hybrid iron and carbon nanoparticles is determined mainly by distance between the electrodes.For a short distance that the plasma is touched with the liquid surface the diameter of nanoparticles is about 10 nm,and for a long distance that the plasma is not touched with the liquid surface,the diameter is reduced to 3-5 nm.Frequency of power during the range of 100-1200 Hz has no obvious effect on the diameter distribution.
