What is Electrochemistry?
Electrochemistry involves the application of a voltage across a pair of electrodes in contact with a number of liquid reactants. This electrical potential induces electron transfer between the electrode and the reactants, thereby stimulating a chemical reaction.
The key advantage of electrochemistry over traditional synthetic chemistry is in the area of oxidation and reduction and enables a large variety of atom efficient chemical transformations to be performed easily
Electrochemistry can be performed in a variety of different methods.
- Potentiostatic mode (control voltage)
- Galvanostatic mode (control current)
When performing a continuous electrochemical reactions there are a number of variables to consider.
- the nature of the electrode
- the voltage/current applied
- whether the chemistry is performed at the anode or cathode
- whether the electrodes are simply either side of the cell (undivided) or are separated (e.g. by an ion permeable membrane, divided)
There are several features of electrosynthesis that are often cited as being environmentally favourable. Electrochemistry has high atom efficiency and low waste.
- Electrons flowing as current may be regarded as one of the reagents.
- The electrodes may be regarded as heterogeneous catalysts that are easily separated from the products.
- Supporting electrolyte and electrochemically active mediator species may be regenerated electrochemically and recovered.
- The amount of electrolyte required is reduced.
Redox reactions are of fundamental importance in chemical science and are widely used in synthetic organic chemistry. Oxidation or reduction processes typically stoichiometric amounts of oxidants or reductants. Though these approaches are reliable for producing target compounds this leads to the generation of hazardous waste, posing environmental concerns to the widespread application and upscaling of these methods.
Benefits of Flow Electrochemistry
The benefits of flow chemistry over traditional batch techniques are widely known, all of these translate equally to flow electrochemistry. Most of these benefits come from the precise control of reaction parameters that flow chemistry offers.
By controlling factors such as temperature, mixing, stoichiometry and reaction times, we can enhance the control of our chemical reactions. In a flow electrochemistry reactor, we can increase this control further over traditional batch electrochemical techniques.
An important benefit of a continuous electrochemistry flow cell over a traditional standard electrochemical cell is the distance between the electrodes. In a flow cell this is significantly smaller allowing for the precise control of the number of electrons into and out of the reactive species. This also lowers the requirement for additives and electrolytes.
