Designing CdS-Based Ternary Heterostructures Consisting of Co-Metal and CoO Cocatalysts for Photocatalytic H Evolution under Visible Light.

Heterostructure formation is an effective method used for designing photocatalysts that solve problems caused by photoexcited charge recombination phenomena associated with the photocatalytic water redox reaction. This work reports a new Co-metal-incorporated ternary heterostructured photocatalyst, CdS/CoO/Co-metal, which enhanced charge separation to increase photocatalytic H evolution 30.5-fold in comparison to pure CdS under visible light.
