ABSTRACT

The quantum electrochemistry area includes definitions and concepts from various fields of science, such as chemistry, physics, mathematics, electricity, mechanics, and engineering. The beginnings of quantum electrochemistry could be mentioned in 1931 when the first application of quantum mechanics to electrochemical reactions was made by Gurney in his paper "The Quantum Mechanics of Electrochemistry," published in Proceedings of Royal Society. One of the pioneers of quantum electrochemistry was Dogonadze, considered as the first scientist that recognized electron transfer reactions as quantum mechanical transitions between two electronic states. The transfer of the electron is fast and takes place at a fixed position of the solvent, following a mechanism where first the solvation layer achieves a configuration between initial and final charge states, afterward the electron is transferred, and the system goes to its new equilibrium state.
