本文介绍了一种以洋葱鳞片为模板制备重金属MS（M=Ag、Cd和Pb）纳米粒子的新方法。Ag 2S纳米颗粒的直径分布在10-20 nm的范围内。CdS空心纳米粒子的直径分布在85-100 nm的范围内。还可以制备直径在7-10 nm范围内的PbS纳米颗粒。该方法操作简单，条件温和，在纳米材料的合成中具有潜在的应用价值。
This paper describes a novel and facile method for preparing the heavy metal MS (M=Ag, Cd and Pb) nanoparticles by bio-template of the squama inner coat of onion. Ag2S nanoparticles exhibit a diameter distribution in the range of 10–20 nm. CdS hollow nanoparticles exhibit a diameter distribution in the range of 85–100 nm. PbS nanoparticles with diameters in the range of 7–10 nm can also be prepared. Because of simple operation and mild conditions this method will have potential application in synthesizing nanoscale materials.
