Overpotential can be divided into many different subcategories that are not all well defined. For example, "polarization overpotential" can refer to the electrode polarization and the hysteresis found in forward and reverse peaks of cyclic voltammetry. A likely reason for the lack of strict definitions is that it is difficult to determine how much of a measured overpotential is derived from a specific source. Overpotentials can be grouped into three categories: activation, concentr… WebOxygen Evolution Reaction (OER) OER is a crucial process in energy conversion and …
