Electrode on which an electrochemical reaction occurs
In
electrochemistry , the working electrode is the
electrode in an electrochemical system on which the
reaction of interest is occurring.
[1]
[2]
[3] The working electrode is often used in conjunction with an
auxiliary electrode , and a
reference electrode in a
three-electrode system . Depending on whether the reaction on the electrode is a
reduction or an
oxidation , the working electrode is called
cathodic or
anodic , respectively. Common working electrodes can consist of materials ranging from
inert metals such as
gold or
platinum , to inert
carbon such as
glassy carbon ,
boron -doped diamond
[4] or
pyrolytic carbon , and
mercury drop and film electrodes.
[5] Chemically modified electrodes are employed for the analysis of both organic and inorganic samples.
