The electrochemical reaction part is composed of a three-electrode system (working electrode, counter electrode, reference electrode) or a two-electrode system (working electrode, counter electrode) and an electrolyte. During the synthesis process, the conductive substrate is used as the working electrode, and under the action of the electric field force, metals / non-metals in the electrolyte are deposited on the conductive substrate to obtain the product.

The synthesis - testing of the self-supporting catalytic material can operate automatically and continuously, without the need for manual intervention during the process, avoiding inaccurate synthesis - testing results of the self-supporting catalytic material caused by manual operation. At the same time, the influence of the external environment on the synthesis - testing is consistent, and there will be no large deviation in the synthesis - testing results of the self-supporting catalytic material; the self-supporting catalytic material that has completed the test can be reliably stored in the recovery container 14;
