trodes etc. Metal electrodes are the electrodes of choice for oxidation/re-
duction of aliphatic compounds with functional groups. Such compounds
are hard to oxidize on inert electrode materials. Due to surface adsorption
of the target compound on metal electrodes the activation energy barrier
for the reaction is lowered allowing oxidation/reduction at much lower po-
tential. Due to the fact that the reactant remains at the WE surface or a
metal oxide layer is formed the electrode is deactivated and needs a
pulsed potential to continuously clean and regenerate an oxide-free metal
surface for the reaction.
