In this work, worm-like SnS2 nanoparticles were prepared by a hydrothermal process. And then their photocatalytic activity was explored for the restoration of effluent containing Cr (VI). The results indicate that the product obtained is hexagonal SnS2 nanoparticles and adopts a worm-like morphology with length of approximate 6 nm and diameter of 3 nm. Moreover, the as-prepared SnS2 nanoparticles possess high photocatalytic activity for the visible light-driven reduction of Cr (VI). When the concentration of Cr (VI) is 4 × 10−4 mol/L, 99% Cr (VI) can be reduced over the as-prepared SnS2 nanoparticles within 30 min under visible irradiation.
