I. What is Marcus theory
Electron transfer is very important chemical process in various systems. There are few models to explain electron transfer reactions. Among them a useful model is dividing charge transfer reactions into outer-sphere and inner sphere reactions according to the interactions with the electrode.
In case of outer-sphere reactions, instead of molecule bonding directly with electrode, electrons are exchanged through tunneling effect, so the original coordination spheres are maintained. On the contrary, inner sphere reactions make bonds with electrode (orbital hybridization) directly and exchange electrons for charge transfer reactions. Reduction of oxygen and the oxidation of hydrogen at Pt wire are representative inner sphere reactions.
Marcus theory can be applied when the charge transfer reactions are outer sphere reactions. Since it does not make a bond with electrode, outer sphere reactions are almost unaffected by the type of electrode metal.
