For most standard tests, the working electrode is a bismuth or mercury film electrode (in a disk or planar strip configuration). The mercury film forms an amalgam with the analyte of interest, which upon oxidation results in a sharp peak, improving resolution between analytes. The mercury film is formed over a glassy carbon electrode. A mercury ...
Industrial Standards for Prebaked Carbon Anodes [4] [5] [6] Property Standard Range; Baked apparent density: ISO 12985-1: 1.53-1.64 gcm-3 Electrical resistance: ISO 11713: 55-62 μΩ for pressed anodes Compressive strength: ISO 18515: 40-48 MPa Young's modulus: RDC-144: 3.5-5.5 GPa Tensile strength: ISO 12986-1: 8-10 MPa for pressed anodes ...
QREs are also more affordable than other reference electrodes. To make a quasi-reference electrode (QRE): Insert a piece of silver wire into concentrated HCl then allow the wire to dry on a lint-free cleaning cloth. This forms an insoluble layer of AgCl on the surface of the electrode and gives you an Ag/AgCl wire.
Equatic’s process combines electrolysis with direct air capture to provide two valuable products, creating a dual-revenue stream. Its clean hydrogen production will help subsidize the cost of carbon removal, quickly bringing it down to less than $100 per tonne before 2030. The OSAs will be manufactured at a San Diego electroplating facility.
Simple scheme of the apparatus for electro-oxidation process. The set-up for performing an electro-oxidation treatment consists of an electrochemical cell.An external electric potential difference (aka voltage) is applied to the electrodes, resulting in the formation of reactive species, namely hydroxyl radicals, in the proximity of the electrode surface.

The electrodes are heat pressed onto the PEM. Commonly used materials for these electrodes are carbon cloth or carbon fiber papers. [3] NuVant produces a carbon cloth called ELAT which maximizes gas transport to the PEM as well as moves water vapor away from the PEM.
The electrochemical reduction of carbon dioxide, also known as CO2RR, is the conversion of carbon dioxide (CO 2) to more reduced chemical species using electrical energy. It represents one potential step in the broad scheme of carbon capture and utilization .
This isolates the undesired redox events taking place at the auxiliary electrode. During bulk electrolysis, the analyte undergoes a redox event at the working electrode. If the system was open, then it would be possible for the product of that reaction to diffuse back to the auxiliary electrode and undergo the inverse redox reaction.
