Water splitting
![](https://commons.wikimedia.org/wiki/Special:FilePath/Electrolysis_of_Water.png?width=300)
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.
