| Abstract: | An efficient interface-hydrothermal approach is developed to synthesize Sn3S4/graphene sheet composites (SSGSCs), where the graphene sheets (GSs) are separated by fine Sn3S4 nanoparticles (NPs) well-dispersed onto their surfaces. The SSGSCs are investigated as electroactive materials for electrochemical capacitors (ECs) application. Due to the positive synergistic effect of GSs and Sn3S4 NPs, the unique SSGSCs electrode owns the ability to deliver large specific capacitance and good electrochemical stability at high rates. Moreover, the method we proposed here provides a universal and simple approach to synthesize other metal sulfides/GSs composites for ECs and even for Li-ion battery applications. |
