金属ナノ触媒の表面構造制御及び製造方法
Document Type and Number:
Japanese Patent JP5705981
Kind Code:
B2
Abstract:
The present disclousure relates to a surface structure control and preparation process for a metal nanocatalyst involving a metal nanocatalyst. The present disclousure provides a surface structure control and continuous preparation system for a metal nanocatalyst, a metal nanocatalyst having an open surface structure and high surface energy, and a surface structure control and a preparation process thereof. The system is provided with a nucleation electrolytic cell, a distribution valve, at least two growth electrolytic cells, with two ends of the distribution valve being connected to an output port of the nucleation electrolytic cell and to input port of all the growth electrolytic cells, respectively. The metal nanocatalyst having an open surface structure is a single metal nanoscale crystal and has a high density of terrace atoms or active sites on the surface thereof. The precursor reaction solution is injected into the nucleation electrolytic cell, and a nucleation programmed potential is applied to one pair of electrodes in the nucleation electrolytic cell to obtain a nucleation reaction solution having the metal crystal nucleus formed, which is conveyed to the growth electrolytic cell through the distribution valve, a growth programmed potential is applied to one pair of electrodes in the growth electrolytic cell to obtain a metal nanoscale crystal having an open surface structure; controlling the growth time to obtain a reaction solution, and collecting a product by centrifugation.
