g-C3N4 (2D)/CdS (1D)/rGO (2D) dual-interface nano-composite for excellent and stable visible light photocatalytic hydrogen generation

A 2D/1D/2D dual-interface nano-heterostructure configuration in the form of CdS nanorods sandwiched between g-C3N4 and rGO sheets with intimate interfacial contact show excellent photocatalytic H2 generation rate of ∼4800 μmol h−1 g−1, with quantum efficiency of 11.1% at 420 nm under visible-light irradiation.422
