利用微波等离子体在液体中以锌电极为原料高效合成了纳米粒子。以乙醇为原料合成的纳米锌颗粒为球形或六方柱状，其产率为3.3g/h，每1 mg的能耗为267J/mg。而在纯水中合成的纳米颗粒由锌和氧化锌组成。锌通过加热或时间的推移与水反应生成氧化锌，释放氢气。放置在距电极1 mm处的上圆盘以及与等离子体点火同时产生的气泡在纳米颗粒的合成中起着关键作用。(C)2010爱思唯尔B.V.保留所有权利。
Nanoparticles are synthesized efficiently from zinc electrode by microwave plasma in liquid. The nanoparticles synthesized from alcohol resulted in pure zinc particles in the shape of spheres or hexagonal cylinders with a production rate of 3.3 g/h, and energy consumption of 267 J/mg for 1 mg. Whereas the nanoparticles synthesized in pure water are composed of Zn and ZnO. The Zn reacts with water through heat or the passage of time to become ZnO, releasing hydrogen gas. An upper disk placed 1 mm away from the electrode along with the bubbles generated simultaneously with the plasma ignition plays a key role in the synthesis of nanoparticles. (C) 2010 Elsevier B.V.
