Magnetically Separable CdS/ZnFe2O4 Composites with Highly Efficient Photocatalytic Activity and Photostability under Visible Light
Source abstract
Abstract
Novel CdS/ZnFe 2 O 4 composites were prepared through a two-step hydrothermal process. The homogeneous ZnFe 2 O 4 nanoparticles are decorated on the self-assembled CdS spheres. Compared to those of pure CdS and blank ZnFe 2 O 4, the photocatalytic activity and stability of the magnetically separable CdS/ZnFe 2 O 4 composites are considerably increased. The results of photoluminescence and electrochemical impedance spectroscopy further validate that the performance enhancement results from the construction of heterojunction structure, leading to high charge separation efficiency. On the basis of the calculation and the trapping test, a heterojunction photocatalytic mechanism is proposed.
