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

Abstract

For the first time, ferrous phosphide (Fe₂P) is used as an active noble metal-free cocatalyst for photocatalytic H₂ production under visible light in water. The rate of H₂ 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.
