16 Electrochemically Enabled Sustainability
charge transfer processes that occur at the electrode/electrolyte interface.
Electrode kinetics is enhanced by materials, which minimise the overpoten-
tial at which one particular reaction can proceed. One can evaluate the elec-
trocatalytic activity of various materials by comparing the current generated
at a given overpotential. On its turn, mediated electrocatalysis is the variety
of effects exerted by a redox system in the homogeneous phase, the redox
system being eventually regenerated in a heterogeneous process at the elec-
trode. Mediated electrocatalysis involves an interaction between the media-
tor, the electrode, and the substrate molecule, for example, carbon dioxide. As
a result, the reduction ...
