Electrochemical synthesis, also known as electrosynthesis, is a process that involves the use of a potentiostat or galvanostat to drive current through an electrochemical cell to force a chemical reaction to produce a desired product. This technique can be used to synthesize a wide range of materials, including metals, alloys, polymers, various chemicals and even pharmaceuticals. Electrosynthesis can take place on a bench scale or on an industrial scale.

Gamry Advantages

Gamry Instruments has a large variety of potentiostats/galvanostats for electrosynthesis. All of our potentiostats/galvanostats are isolated from Earth ground, making it easy to run syntheses in grounded cells. This can be especially useful if you are running your reactions in a reactor vessel for elevated temperature or pressure. Finally, our software development kits (toolkits) allow you to customize your setups, experiments, and data analysis. This customization is especially useful if you need to control the potentiostat in a process control environment.

More Details on Electrochemical Synthesis

Electrochemical synthesis involves the use of an electrochemical cell which contains two or three electrodes. A two-electrode system contains a working electrode and counter electrode. The advantage of two-electrode setups is that they are easier to maintain and don’t require a reference electrode but they can suffer from accuracy and control problems if the synthesis procedure is not well understood.

A three-electrode setup, utilizing a reference electrode, allows for more accurate control of the synthesis. Here, the voltage of the working electrode is measured against the stable reference electrode. This helps eliminate unwanted side reactions.

Electrosynthesis techniques have some advantages over traditional chemical synthesis techniques. They can be run at lower temperatures and pressures and can be run in aqueous media as opposed to more hazardous organic solvents. They can also accumulate less waste since there is greater control over the reaction.


Recommended Systems

Our standard lineup includes instruments capable of outputting 600 mA, 1 A, 3 A, and 5 A. The Reference 3000 combined with the Reference 30k Booster then lets you apply and measure up to +/-30 A of current at +20/-2.5 V. If 30 A is not enough, the LPI1010 Load/Power Supply Interface allows us to expand to even higher currents when necessary. Our LPI1010 combines the signal generation and accurate measuring capabilities of an Interface 1010E with an electronic load (or power supply) to work at higher currents (>30A).
