Figure 6: Mechanism of charge separation in CdS-TiO2 composite semiconductors (a). Mechanism of photocatalytic H2 evolution on CdS-intercalated layered composites loaded with Pt. Photogenerated electrons in CdS are quickly transferred to host layers through the nanostructure, preventing charge recombination. Readapted from [1].
