Oxygen evolution reaction中文
WebMechanism of oxygen evolution. From the reaction formula above, it is clear that oxidation of water to O 2 requires abstraction of 4 electrons. Since the photochemistry is a 1 photon/1 electron event (Einstein's Law), this requires a mechanistic interface between the 1-electron photochemistry, and the 4-electron oxidation process.
