 Pt Counter Electrode:

The Pt counter electrode is an essential element in electrochemical systems that complements the working electrode. Its primary function is to facilitate the flow of current during electrochemical reactions. Made from platinum, the counter electrode possesses excellent electrical conductivity, stability, and corrosion resistance.

 The Pt counter electrode ensures an efficient and complete electrical circuit, enabling accurate measurement of the working electrode potential. Its inert nature prevents unwanted reactions or interference, allowing precise determination of the desired electrochemical processes.

 Platinum Mesh Electrode:

The platinum mesh electrode, also known as the mesh-supported electrode, is a specialised form of the Pt counter electrode. It features a mesh structure made of platinum, providing several advantages over traditional solid Pt counter electrodes.

 The platinum mesh electrode offers a larger surface area, promoting enhanced mass transport of reactants and products during electrochemical reactions. The increased surface area improves the electrode's efficiency, making it particularly useful in processes requiring high current densities.

 Moreover, the mesh structure allows for better gas evolution, reducing bubble formation and minimizing the impedance caused by gas bubbles adhering to the electrode surface. This feature is advantageous for electrochemical applications involving gas evolution reactions, such as water electrolysis or fuel cell systems.

 The platinum mesh electrode finds applications in various fields, including electrocatalysis, energy storage, and environmental monitoring. Its unique structure and properties make it an attractive choice for researchers and engineers seeking improved performance and efficiency in electrochemical systems.

 Summary:

The Pt counter electrode and platinum mesh electrode are essential components in electrochemical systems, contributing to enhanced performance and accurate measurements. The Pt counter electrode ensures complete electrical circuits, while the platinum mesh electrode offers increased surface area and improved mass transport. Together, these electrodes empower advancements in fields like electrocatalysis, energy storage, and environmental applications, propelling the development of efficient and sustainable electrochemical technologies.
