| 中文摘要: |
| 双子表面活性剂由于其特殊的两亲结构可以作为纳米金颗粒的表面稳定剂，但双子表面活性剂结构中的连接基团的不同对纳米金的粒径大小及稳定性影响显著，本文制备了16-n-16（n=2, 3, 4和6）型双子表面活性剂稳定的金纳米溶胶， 考察了体系pH值对纳米金稳定性的影响，还测试了其对4-硝基苯酚加氢还原体系的催化效果，结果表明，16-4-16和16-3-16对纳米金的稳定性效果较好，所制备的纳米金中，16-3-16-AuNPs在不同pH值的环境中稳定性最好，而16-4-16-AuNPs的在4-硝基苯酚加氢还原反应中的催化活性最佳。 |

| Gemini surfactants can be used as surface stabilizers for preparing gold nanoparticles due to their special structures. The particle size and stability of gold nanoparticles were affected by the different spacers in the structure of gemini surfactants significantly. Gold nanoparticle colloids were prepared with the gemini surfactants (16-n-16, n=2, 3, 4 and 6). The effect of pH value on the stability of gold nanoparticles in the dispersion systems was investigated. The catalytic property of the gold nanoparticles on hydrogenation of 4-nitrophenol was studied. 16-4-16 and 16-3-16 were better for stabilizing gold nanoparticles. 16-3-16-AuNPs in different pH environment showed the best stability. The catalytic activity of 16-4-16-AuNPs in 4-nitrophenol hydrogen reduction reaction was better than others. |
