▎ 摘　　要

Reduced graphene oxide (RGO) nanosheet-supported SnS2 nanosheets are prepared by a one-step microwave-assisted technique. These SnS2 nanosheets are linked with each other and dispersed uniformly on RGO surface. The SnS2-RGO sheet-on-sheet nanostructure exhibits good electrochemical performances as an anode material for lithium ion batteries. It shows larger-than-theoretical reversible capacities at 0.1 C and excellent high-rate capability at 1 C and 5 C. The composite is also for the first time identified as an excellent visible light-driven catalyst of rhodamine B and phenol with high degradation efficiencies. The removal rates of rhodamine B and phenol are 100 and 83.2%, respectively, for the SnS2-RGO composite, whereas these values are only 64.8 and 51.5% for pristine SnS2 after the same irradiation times. The outstanding electrochemical or photocatalytic performances of the composite have been attributed to the complementary
