The design of a synthesis strategy for metal nanoparticles by templating dense microemulsions is proposed. Particle size is controlled by surfactant size rather than by microemulsion composition. The strategy was demonstrated with various systems with different surfactant: cationic, anionic and non-ionic and of different sizes. Formulations were determined using the microemulsion phase diagrams. Synthesis was demonstrated for platinum nanoparticles with some examples for gold. The nanoparticles were subsequently extracted from the microemulsion by absorption onto a carbon support, after which the surfactant was recycled.
提出了一种通过模板化致密微乳液合成金属纳米颗粒的策略。颗粒尺寸由表面活性剂尺寸控制，而非微乳液组成。该策略在具有不同表面活性剂（阳离子、阴离子和非离子）及不同尺寸的各种体系中得到了验证。使用微乳液相图确定配方。以铂纳米颗粒为例进行了合成演示，并给出了一些金纳米颗粒的示例。随后通过吸附到碳载体上从微乳液中提取纳米颗粒，之后表面活性剂可循环利用。
