A highly efficient photocatalyst based on layered g-C3N4/SnS2 composites
Abstract
\n\nIn this report, the layered g-C3N4/SnS2 composite was successfully fabricated by a facile hydrothermal route. \n\n\n\nThe 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%). \n\n\n\nThe 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. \n\n\n\nOur work demonstrates that the layered g-C3N4/SnS2 can be considered as an exceptional candidate for highly-efficient photocatalyst.\n
