electrode
/ɪˈlɛktroʊd/
Definition
A conductor through which electric current enters or leaves an electrochemical cell, facilitating the chemical reactions needed to capture CO2.
Etymology
The word was coined in the 19th century by scientist Michael Faraday by combining the Greek 'elektron' (meaning amber, the source of static electricity) and 'hodos' (meaning way or path).
In the news
In the article, specialized manganese dioxide electrodes are used in a battery-like device to alter the pH of a solution, allowing it to absorb carbon dioxide from the air. Their design is essential for the device's ability to efficiently perform direct air capture.
