Synthesis of core-shell SnS2/CdIn2S4 heterojunction photocatalyst for visible light driven hydrogen evolution

In this paper, the core-shell SnS2/CdIn2S4 heterojunction was synthesized by hydrothermal method through in situ synthesis of SnS2 nanosheets on the surface of CdIn2S4 nanoflower. The composites have larger specific surface area and can provide more reactive sites. CIS/S-11 exhibits the highest photocatalytic activity rate of 345.2 mu mol/g/h, which is 3.8 times higher than that of pristine CdIn2S4. The incorporation of SnS2 show high resistance to photogenerated carriers recombination rate in CdIn2S4, and consequently enhanced the efficiency of photocatalytic hydrogen production driven by visible light.

Automated summary

The core-shell SnS2/CdIn2S4 heterojunction was successfully synthesized through in-situ synthesis of SnS2 nanosheets on CdIn2S4 nanoflower. The composites have larger specific surface area and more reactive sites, leading to improved photocatalytic activity. CIS/S-11 showed the highest photocatalytic activity rate of 345.2 mu mol/g/h, indicating significantly enhanced efficiency of photocatalytic hydrogen production compared to pristine CdIn2S4.
