Make Hydrogen while the Sun Shines: The Photoelectrolysis of Water Using Oxide Semiconductors

Abstract:

Article Preview

The principles of photoelectrochemical generation of hydrogen using inorganic semiconductor/water interfaces are first outlined. Advantages in the use of oxide semiconductors for solar hydrogen generation are then enumerated. The requirements for the water splitting reaction in terms of the semiconductor photocatalyst(s) are then elaborated. Finally, preliminary results are presented on the use of electrodeposited p-Cu2O films for hydrogen generation in a twin-compartment photoelectrochemical cell using visible light and sacrificial reducing agents in the (dark) anode compartment.
