It is a challenge to develop microemulsions which can serve as nanoreactors for the synthesis of nanoparticles and chemical reactions at high temperature. In this work, a class of novel high temperature microemulsions consisting solely of ionic liquids have been designed and prepared for the first time. It is found that nanoscale droplets formed in the ionic liquid microemulsions can be maintained up to 200 °C, and the size distribution of the droplets can be easily tuned by selection of the ionic liquids and varying compositions of the systems. By using such microemulsions as nanoreactors, porous metals such as Pt have been prepared at 180 °C without using any purposely added reductant.

纳米反应器可在高达200°C的温度下稳定：一类仅由离子液体组成的高温微乳液†

开发可用作纳米颗粒合成和高温化学反应的纳米反应器的微乳液是一个挑战。在这项工作中，首次设计和制备了仅由离子液体组成的一类新型高温微乳液。已经发现，在离子液体微乳状液中形成的纳米级液滴可以保持至200℃，并且可以通过选择离子液体和改变系统组成来容易地调节液滴的尺寸分布。通过使用这种微乳液作为纳米反应器，在不使用任何故意添加的还原剂的情况下，在180°C下制备了多孔金属（如Pt）。
