Molybdenum disulfide (MoS2) is one of the promising candidates for battery and supercapacitor electrode materials because of its graphene-like two-dimensional structure. The layered structure and weak van der Waals interaction between neighboring MoS2 layers can provide large surface area and adequate transport channel for electrochemical charge storage. However, the low electrical conductivity of common 2H-MoS2 with large bandgap restrict their applications in the energy conversion and storage fields. In contrasts, metallic 1T-MoS2 has different electron configuration to 2H-MoS2 and exhibits excellent electrical conductivity. In this study, metallic 1T-MoS2 nanosheets were synthesized on graphite foil (GF) substrate by a facile hydrothermal method using ammonium persulfate. SEM, XRD and XPS analysis were used to investigate the structures of 1T-MoS2. Also, electrochemical properties of the 1T-MoS2/GF electrode were evaluated by CV, GCD and EIS in 3-electrode configuration. |
