The photocatalytic water splitting for hydrogen evolution demonstrated that such structural design can synergistically trigger remarkably improved visible-light-driven photocatalytic activity. Photocatalytic H2-evolution at 2107.5 μmol g−1 h−1 was achieved on this CdS/QDs/ZnIn2S4 architectures under visible light irradiation, exceeding those of bare CdS nanorods and pure ZnIn2S4 nanosheets by a factor of 26 and 62, respectively. This highly efficient photocatalytic activity arises from the effective charge separation and favourable electron mediator of MoS2 QDs. The Z-scheme charge separation mechanism was verified by the ESR, PL-TA and organic electron acceptor test.||URI:||https://hdl.handle.net/10356/150386||ISSN:||0169-4332||DOI:||10.1016/j.apsusc.2019.144406||Rights:||© 2019 Elsevier B.V.
