Engineering Zn<sub>1–<i>x</i></sub>Cd<sub><i>x</i></sub>S/CdS Heterostructures with Enhanced Photocatalytic Activity Kui Li Rong Chen Shun-Li Li Shuai-Lei Xie Long-Zhang Dong Zhen-Hui Kang Jian-Chun Bao Ya-Qian Lan 10.1021/acsami.6b02765.s001 https://acs.figshare.com/articles/journal_contribution/Engineering_Zn_sub_1_i_x_i_sub_Cd_sub_i_x_i_sub_S_CdS_Heterostructures_with_Enhanced_Photocatalytic_Activity/3412384 Various 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. 2016-05-12 00:00:00 5 mg photocatalyst evolution rate 5 mg H 2 Enhanced Photocatalytic Activity photocatalytic stability 100 h CdS quantum dots synthesis method Zn 420 nm quantum efficiency
