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 platinum wire electrode has a relatively small area ，which is suitable for use in combination with a disc-shaped working electrode. The platinum wire electrode has a variety of shapes and structures, which can be bent according to the length of the platinum wire to be used with various types of electrochemical cells. The insulating rod material of the platinum wire electrode can be PTFE or PEEK rod. As the working electrode undergoes an oxidation or reduction reaction, a gas evolution reaction or a reverse reaction of the working electrode ...

Glassy carbon electrode is one of the most widely used working electrodes, and it is a better inert electrode. Glassy carbon electrode has many advantages such as good conductivity, high hardness, high finish, high hydrogen overpotential, and wide polarization range. Its chemical properties are very stable, and it can be used as an inert electrode for direct anodic dissolution testing, and voltammetric determination of cathodes and variable valence ions. Using glassy carbon electrodes as the substrate, chemically modified electrodes can also be prepared. There are four types of insulating rods for glassy carbon electrode jackets. Glassy carbon electrodes are divided into straight type, L type, T type and detachable type. The straight glassy carbon electrode material faces vertically downwards, and the research material is coated on the glassy carbon material surface for testing. The reference electrode is matched with a curved luggin capillary salt bridge close to the material surface ...

In electrochemistry, in order for a specific reaction to occur, a stable electric potential needs to be applied to the working electrode. The potential of the working electrode should always be accurately controlled. This is why a reference electrode is needed as a potential reference standard. Common reference electrodes include Silver Silver Chloride Ag/AgCl reference electrode, saturated calomel electrode,Hg/HgO reference electrode, Hg/Hg2SO4 reference electrode and Non aqueous Ag+ reference electrode,etc. The silver-silver chloride (Ag/AgCl) electrode is the most commonly used reference electrode. Compared with calomel electrodes that use mercury and its salts, Ag/AgCl electrodes are more environmentally friendly. Its electrode potential also has sufficient stability, reliability and reproducibility. Special attention should be paid to maintenance and storage when using Ag/AgCl reference electrode. Before use rinse it with deionized water. If air bubbles are present around the poro...

  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 photoelectrocata...
