Enhanced photocatalytic hydrogen production in water under visible light using noble metal-free ferrous phosphide as an active cocatalyst

For the first time, ferrous phosphide (Fe2P) is used as an active noble metal-free cocatalyst for photocatalytic H-2 production under visible light in water. The rate of H-2 production can be enhanced by more than 30 times through loading of Fe2P on CdS nanorod surfaces. Efficient charge transfer between CdS and Fe2P might be the key factor for the high photocatalytic activity.
