Abstract

The invention discloses a device for preparing a metal catalyst by using plasma. The device comprises a reaction chamber, a metal plate electrode and a multi-needle electrode are arranged in the reaction chamber, the metal plate electrode and the multi-needle electrode are oppositely arranged, and a dielectric plate is pressed and covered on the metal plate electrode. According to the invention, uniform, large-area and high-density plasmas are generated, the metal catalyst can be prepared with high efficiency and high quality, transition from corona discharge to spark discharge can be effectively avoided, excessive sintering in the catalyst preparation process is avoided, and preparation of the catalyst is facilitated. The device is simple and convenient in design, low in cost and convenient to disassemble, and can be applied to other fields of discharge plasma application.

Description

technical field [0001] The invention relates to the field of catalyst preparation, in particular to a device and method for preparing metal catalysts by using plasma. Background technique [0002] Metal catalysts are widely used in various industries in industrial production, such as petrochemical industry, synthetic ammonia industry, electroplating industry, etc. For metal catalysts, when the metal is uniformly dispersed on the carrier in the form of single atoms, it is the ideal state of the metal catalyst. The preparation methods include impregnation method, atomic deposition method, reduction method, solid phase melting method, etc., but these methods are usually cumbersome and time-consuming in the preparation process, and require the use of a large amount of toxic and harmful reagents, which is not conducive to environmental protection. Contents of the invention [0003] The invention provides a device and method for preparing a metal catalyst by using plasma. The pr...
