Method for preparing metal particles through continuous electrochemical deposition

Abstract

The invention discloses a method for preparing metal particles through continuous electrochemical deposition. The method comprises the main steps: firstly, by controlling electrodeposition parameters,evenly-dispersed metal particles are electrodeposited on a movable substrate; then the movable substrate carry the electrodeposited metal particles, and the substrate and materials on the substrate are cleaned or subjected to surface treatment; and finally, the particles on the surface of the substrate are stripped through methods such as physical stripping, and the particles are dispersed in a solution to be collected. The method has the advantages that the metal particles are prepared through an electrodeposition electronic reduction method, wherein the particle diameter of the metal particles is even, the metal particles are evenly dispersed, and the surfaces of the metal particles are free of active agents; and contact force between the particles and the substrate is small so that theparticles can be collected through simple physical stripping, in the whole synthesis process, the particle size is controllable, an electrolyte can be reutilized, compared with a traditional method for synthesizing the metal particles, the cost is low, and the size is controllable.

Description

technical field

[0001] The invention relates to the field of synthesis of metal particles, specifically, the invention relates to metal particles with low contact force and a method for preparing the corresponding metal particles by adjusting the particle size through continuous electrochemical deposition. Background technique

[0002] Metal particle materials are an important part of metal materials. In recent years, with the discovery of various novel properties of metal particles, the field of metal particles has achieved vigorous development and has become a key basic material for the preparation of various new functional materials. The development of preparation methods for metal particles is the basis for the development of metal science. Traditionally, there are two main ways to prepare metal particles: one is chemical method, including liquid phase reduction method, high temperature pyrolysis method and so on. The liquid-phase reduction method includes hydrothermal,...
