Visible and near-infrared light responsed Sn1−x Bi x S2nanosheets was synthesised via a simple hydrothermal method. Rhodamine B was adopted to evaluate the degradation efficiency of the as-prepared samples. Experimental results showed that the doping content of Bi3+ could obviously affect the degradation efficiency of SnS2. It was first increased and then decreased with increasing the Bi3+ content under the visible light irradiation. When the mole fraction of doping Bi3+ was 5%, the as-prepared Sn0.95Bi0.05S2 with a bandgap of 0.38 eV had the highest degradation efficiency of 95.9% in 120 min. Moreover, the as-prepared composites possessed more effective electron–hole pair separation than that of pure SnS2. In addition, a possible degradation mechanism of the as-prepared Sn0.95Bi0.05S2 was proposed.
