Electrode mechanism considering reduction from adsorbed state and oxidation from dissolved state

Redox processes in which oxidation and reduction take place from different state are important systems in many physiological and industrial processes. Rechargeable batteries, for example, are system in which water soluble ions get created from metals in atomic state. Also, many physiological processes of amphiphilic enzymes can be regarded to take occur redox transformation from adsorbed and dissolved state, too. In this work, we give short overview on the model of simple redox mechanism in which reduction occurs from adsorbed state, while re-oxidation happens from dissolved state, with mass transfer occurring via diffusion. This hybrid model is quite relevant to understand the processes in rechargeable batteries and in enzymatic voltammetry
