Summary: The crystal morphology of nanomaterials plays a significant role in their adsorption-photocatalytic activities. In this study, ZnS nanomaterials with different shapes were synthesized using ZnO as templates. It was found that short nanotubes exhibited excellent adsorption performance for methylene blue, while nanosheets showed the highest photocatalytic efficiency. Furthermore, the higher exposure ratio of {100} crystal planes on nanosheets not only resulted in a narrower bandgap but also provided more sites for adsorption and electron/hole trapping.
