Nanosheet-assembled Mn-Co sulfide well-defined hollow nanocubes as advanced electrodes for high performance supercapacitor |
| 초록 |
Supercapacitor is one the most promising electrical energy storage for applying scientific fields such as hybrid vehicle and portable electric device. Hollow structures with nanosheets and binary transition metal sulfides (BTMSs) are two important key factors to enhance the electrochemical performance of electrode materials for supercapacitor. Hollow structures with nanosheets can maximize specific surface area of the electrode material for improved capacitance. The BTMSs, such as manganese-cobalt sulfides have several outstanding advantages; rich redox reactions, the synergistic effects by interaction between metal compounds, and better electrical conductivity than transition metal oxides. Herein, we successfully synthesized the hollow structured manganese cobalt sulfide nanocubes by 3-step process. The morphology, crystallinity and chemical composition of MnxCo3-x[Co(CN)6]2 nanocubes, manganese-cobalt hydroxides, and manganese- cobalt sulfides were confirmed by SEM, TEM, XRD, and FT-IR. |
