Abstract

Background: In this report, the layered g-C₃N₄/SnS₂ composite was successfully fabricated by a facile hydrothermal route.

Methods: The ultraviolet-visible spectroscopy data presented that such layered g-C₃N₄/SnS₂ catalysts showed a remarkable visible-light absorption, hence significantly enhancing the catalytic activity. Particularly, the g-C₃N₄/SnS₂ catalysts showed an outstanding catalytic performance for the degradation of methylene blue (~ 98.1%) under visible light irradiation that is much better than that of pure SnS₂ (~ 86.7%) and pure g-C₃N₄ (~ 67.3%).

Results: The remarkable photocatalytic performance is ascribed to its layer structure resulting in a large surface area, which not only improves the ion transfer rate but also provides abundant surface reaction sites.

Conclusion: Our work demonstrates that the layered g-C₃N₄/SnS₂ can be considered as an exceptional candidate for a highly-efficient photocatalyst.

Keywords: SnS₂, g-C₃N₄, visible light, photocatalysts, methylene blue, highly efficient.
