Novel noble-metal-free Ni12P5/CdS composite was designed and synthesized by a hydrothermal method. The photocatalytic H-2 generation activity of the as-prepared Ni12P5/CdS is 1.93 fold of that of pure CdS under visible light (lambda > 420 nm) irradiation. The enhanced activity of Ni12P5/CdS is ascribed to the improved separation efficiency of photocarriers over a direct Z-scheme mechanism. It provides a potential strategy to improve the photocatalytic H-2 evolution activity of CdS greatly by loading noble-metal-free Ni12P5 as electron co-catalyst via direct Z-scheme mechanism.
