| 摘 要： | 在SDS／Vc／H2O微乳液中用0．001mol·L^-1HAuCl4溶液代替组分水，以Vc作还原剂制备纳米金。紫外一可见光谱和扫描电镜实验结果表明，所制备的金纳米粒子的粒径在5-20nm之间；在固定SDS／Vc的质量比为50／50条件下，粒子的粒径随微乳液中HAuCl4（aq）含量的增加而增加。初步探讨了在SDS／Vc／H2O微乳液中合成纳米金的机制。

| Abstract: | Gold nanoparticles are prepared in O/W microemulsion of SDS/Vc/H2O (0.001 mol?L-1 HAuCl4) system by using Vc as the reducing agent. The size of obtained polygonal gold nanoparticles is from 5 nm to 20 nm,and increases with the content increase of HAuCl4 in O/W microemulsion in the condition of SDS/Vc weight ratio of 50/50. The formation mechanism of gold nanoparticles is discussed in the present paper. |
