Platinum is an inert metal and does not participate in the electrode reaction itself, so it is the first choice for the counter electrode. One of the important parameters of the counter electrode is its surface area. The counter electrode must have a large enough area to support the current conduction generated on the working electrode. Platinum electrodes include platinum sheet electrodes, platinum wire electrodes, and platinum mesh electrodes.

The area of the platinum mesh electrode is smaller than platinum sheet electrode, and it is also suitable for use in combination with large-size sheet-shaped working electrode materials. There are two types of platinum mesh electrodes. Through a special customized process, a platinum mesh counter electrode with a PTFE insulated rod can be made into an integrated platinum mesh counter electrode. The platinum mesh can also be clamped by a replaceable electrode clamp as a counter electrode. At the same time, in some spectral photoelectrocatalytic reactions, platinum mesh is more suitable as a counter electrode because of its porous network structure.

As the working electrode undergoes an oxidation or reduction reaction, a gas evolution reaction or a reverse reaction of the working electrode reaction may occur on the counter electrode. Therefore, in some cases it is necessary to separate the working electrode from the counter electrode. The best way to reduce the interference of the reaction on the counter electrode on the working electrode is to use sintered glass, porous ceramics or ion exchange membranes to isolate the solution in the two electrode regions.
