Introduction
In electrochemistry, electrodes are conductors that make contact with a nonmetallic part of a circuit. They are used in a variety of applications including batteries, electrolysis, and potentiometric analysis. Inert electrodes, such as graphite, platinum, gold, and rhodium, do not participate in chemical reactions and are used to transfer electricity by passing electrons through a solution instead of exchanging ions. Gold electrodes are commonly used in electrochemistry due to their inertness, good conductivity, and resistance to corrosion. They are also used in the fabrication of integrated circuits and other electronic devices.

Detail & Parts
Applications
Electrodes, especially gold electrodes, are widely used in various fields. Some major application areas include:
- Analytical chemistry: Gold electrodes can be used for electrochemical measurements such as potentiometry, voltammetry, and amperometry. They are used for the detection and quantification of a variety of substances, including heavy metals, ions, and organic compounds.
- Battery: Gold electrodes are used as components in different types of batteries, such as lead-acid batteries, zinc-carbon batteries, and lithium-polymer batteries. Their role is to facilitate the flow of electrons and enable the storage and release of electrical energy.
- Electrolysis: During the electrolysis process, the gold electrode acts as an auxiliary electrode. They provide an inert surface for reactions to occur without participating in electrochemical reactions. This allows salts and ores to be converted into metals efficiently.
- Non-aqueous reference electrode: In non-aqueous electrochemistry, gold electrodes can be used as pseudo-reference electrodes. They establish a constant reference potential during experiments and help monitor changes in cell solutions. This application is critical for studying electrochemical reactions in non-aqueous solvents.
Advantages
- Increased masking potential: Gold plating is more compatible with selective plating applications than PVD coating, allowing manufacturers to plate specific areas of a workpiece while leaving others unaffected.
- Lower energy consumption: Gold plating requires a low-voltage electrical current for electrodeposition, consuming less energy compared to PVD, which often occurs at high temperatures. This reduced energy consumption can lower project costs.
- Extended range of applications: Gold, platinum, and glassy carbon (GC) are common electrode materials in RRDEs, but GC is prone to dissolution at high oxidizing potentials, especially in alkaline solutions. Moving to different electrode materials, such as gold, can expand the range of applications for RRDEs.
- Durability and corrosion resistance: PVD Gold Sputtering coating offers superior durability and corrosion resistance compared to other gold coating types. Its ability to retain its sheen and withstand contact with the skin and wear makes it ideal for high-end jewelry, ensuring a longer-lasting lifespan.
