The probe of charging transfer (CT) process can be of vita importance in various fields, including energy generation, energy storage and investigating biological processes.This dissertation focuses on the development of methodology to study complex CT proceses via electrochemical characterization. The static and dynamic charging characterization, oxygen deficiency impact on the CT process as well as performance of non-stoichiometric nanostructured tungsten oxide will be discussed. Additionally, in the aspect of biological process, the iron redox pathway in ferritin is revealed via electrochemical analysis.
