Synthesis and photocatalytic activity of three-dimensional ZnS/CdS composites

- 3D urchin-like ZnS/CdS composites were synthesized via a two-step method.
- The CdS nanoparticles were assembled on the thorns of 3D ZnS urchins.
- The ZnS/CdS composites show excellent photocatalytic degradation activities.
- The modification of CdS on ZnS is responsible for the enhanced property.
