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 (Fe 2 P) 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 by loading Fe 2 P on CdS nanorod surfaces.
