In this study, plasma-induced cathodic discharge electrolysis using a rotating disk anode was conducted in molten LiCl-KCl-CsCl electrolytes, and Ni nanoparticles with diameters of less than 10 nm were obtained. The obtained particles became smaller and more uniform when rotation speed of the disk anode increased until it reached 2,000 rpm; meanwhile, the size of the obtained particle hardly depended on the rotation speed when it exceeded 2,000 rpm. Regardless of rotation speeds, the electrolysis current (0.1-5.0 A) did not affect the size of the particle. The rotating disk anode-type electrolytic cell, therefore, controls the particle growth by the rotation speed of the disk anode.

本研究利用旋转圆盘阳极在熔融LiCl-KCl-CsCl电解质中进行等离子体诱导阴极放电电解，获得了直径小于10 nm的Ni纳米颗粒。当圆盘阳极转速增加至2000rpm时，所得颗粒变得更小且更均匀；同时，当转速超过2,000rpm时，所得颗粒的尺寸几乎不依赖于转速。无论旋转速度如何，电解电流（0.1-5.0 A）都不影响颗粒的尺寸。因此，旋转圆盘阳极型电解池通过圆盘阳极的旋转速度来控制颗粒生长。
