porous Zn<sub>1–<i>x</i></sub>Cd<sub><i>x</i></sub>S/CdS heteorostructures were achieved via in situ
synthesis method with organic amines as the templates. Because of
the larger radius of Cd<sup>2+</sup> than that of Zn<sup>2+</sup>,
CdS quantum dots are formed and distributed uniformly in the network
of Zn<sub>1–<i>x</i></sub>Cd<sub><i>x</i></sub>S. The Zn<sub>1–<i>x</i></sub>Cd<sub><i>x</i></sub>S/CdS heterostructure with small Cd content (10 at%)
derived from ethylenediamine shows very high H<sub>2</sub>-evolution
rate of 667.5 μmol/h per 5 mg photocatalyst under visible light
(λ ≥ 420 nm) with an apparent quantum efficiency of 50.1%
per 5 mg at 420 nm. Moreover, this Zn<sub>1–<i>x</i></sub>Cd<sub><i>x</i></sub>S/CdS heterostructure photocatalyst
also shows an excellent photocatalytic stability over 100 h.
