Hexagonal@Cubic CdS Core@Shell Nanorod Photocatalyst for Highly Active Production of H2 with Unprecedented Stability

A highly effective, low-cost strategy for improved photocatalytic efficiency and stability of CdS is described. Based on the integration of hexagonal-cubic core-shell architecture with nanorod morphology, the concentric CdS nanorod phase junctions (NRPJs) obtained demonstrate extremely high H2 production rate and unprecedented photocatalytic stability.
