CdS quantum dots and tungsten carbide supported on anatase–rutile composite TiO2 for highly efficient visible-light-driven photocatalytic H2 evolution from water

A noble-metal-free CdS/WC/TiO₂ photocatalyst with water-soluble CdS quantum dots (<5 nm) and anatase–rutile composite TiO₂ is highly efficient for H₂ evolution from visible-light-driven photocatalytic water reduction.
