Oxidation and Reduction
... Oxidation occurs when atoms lose electrons. Reduction occurs when atoms gain electrons. These two processes always occur together. In other words, you can’t just let electrons loose into space—they must be grabbed by some other atom. Likewise, you can’t just grab electrons from space—they must be ta ...

Water splitting

Water splitting is the general term for a chemical reaction in which water is separated into oxygen and hydrogen. Efficient and economical water splitting would be a key technology component of a hydrogen economy. Various techniques for water splitting have been issued in water splitting patents in the United States. In photosynthesis, water splitting donates electrons to power the electron transport chain in photosystem II.
