Problems solved by technology

However, the dealloying method needs to prepare alloys with different compositions, and the alloy needs pre-treatment such as annealing to ensure the uniformity of the alloy structure, and the condition control of the dealloying process also seriously affects the structure and shape of the finished material. The treatment and dealloying process is also a time-consuming process

Abstract

The invention discloses a dendritic crystal nickel base catalytic electrode preparation device and method based on 3D printing. The device comprises an industrial personal computer (1), a chemical pump (2), an anode tool electrode (4), a plating liquid nozzle (5), a connecting head (7), a plating tank (8) and a three-dimensional mobile platform (10); the industrial personal computer (1) is used asa three-dimensional motion control system for receiving modeling pattern data of nickel base catalytic electrodes of users and automatically converting to motion control data of the three-dimensionalmobile platform to control the three-dimensional mobile platform to move in X, Y and Z axle directions. Through downwards vertical flowing of plating liquid, dendritic crystal structures are formed on the surfaces of the electrodes to effectively promote the catalytic reaction area of the electrodes.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a preparation device and method for a dendritic nickel-based catalytic electrode based on 3D printing. Background technique [0002] In today's world, the fossil fuels that can meet the energy demand are rapidly declining. At the same time, the environmental problems caused by the combustion products of fossil fuels are gradually destroying the natural environment on which people live and people's life and health. Therefore, the development of efficient and cheap new energy has become a problem that must be solved. Among the new energy sources that have been developed, hydrogen energy is considered to be one of the new energy sources with the best application prospects. At present, among the main hydrogen production methods, electrolysis of water and hydrogen evolution can directly produce relatively high-purity hydrogen, and the energy conversion rate of the ...
