Method for preparing ternary copper-based catalyst through electrolysis

Abstract

The invention relates to the field of copper catalysts, in particular to a method for preparing a ternary copper-based catalyst through electrolysis. The method comprises the following steps of: placing a metal copper electrode and a counter electrode in an electrolyte for pulse electrolysis, applying a pulse current to intermittently generate copper oxide and cuprous oxide on the surface of the metal copper electrode, and stripping the ternary copper-based catalyst from the metal copper electrode. The preparation method is high in preparation efficiency, and the ternary copper-based catalystcan be efficiently and industrially produced; the controllability of the components is stronger, and the preparation of various ternary copper-based catalysts with different proportions of metal copper, copper oxide and cuprous oxide is facilitated; and under the action of a magnetic field, the particle size of the prepared ternary copper-based catalyst has certain controllability, and the ternarycopper-based catalyst with smaller and more uniform particle size can be prepared.

Description

technical field [0001] The invention relates to the field of copper catalysts, in particular to a method for electrolytically preparing a ternary copper-based catalyst. Background technique [0002] Copper is an electrostatic catalyst for direct synthesis of methylchlorosilane. The copper catalyst used for the direct synthesis of methylchlorosilane was initially used as electrolytic copper powder. Due to the compact surface and small specific surface area of ​​electrolytic copper powder, it is difficult to form active centers in the reaction, resulting in low catalytic activity. In recent years, those skilled in the art have developed and reported porous cubic Cu particles, mesoporous Cu 2 The preparation process of O microspheres, flower-like and dandelion-like CuO microspheres, and their properties were tested at the same time. When they were used as catalysts in the catalytic reaction of organosilicon monomer synthesis, due to their special morphology, which increased T...
