| titleOfInvention | ZIF-67 framework-based double-shell sulfide and preparation method and application thereof |
| abstract | The invention discloses a ZIF-67 framework-based double-shell sulfide, and a preparation method and application thereof, which are expressed as CoS/MCo 2 S 4 Wherein the material of the inner shell is CoS, and the material of the outer shell is MCo 2 S 4 M may be Ni, Mn, Fe, Cu and Zn. The method specifically comprises the following steps: a. preparing ZIF-67; b. preparing a core-shell intermediate; c. preparing a double-shell sulfide electrode material; d. assembling: and (3) coating the prepared double-shell sulfide on the surface of the foamed nickel to assemble the supercapacitor. The invention has the structural characteristics of a ZIF-67 framework double-shell layer, contains two different sulfides, and has the characteristics of large specific surface area, many active sites and the like, thereby effectively improving the specific capacity of the supercapacitor. The structure of the invention has stable skeleton firmness and a cavity structure, and can slow down the structural collapse of the electrode material of the super capacitor in the charging and discharging processes, thereby remarkably improving the cycle stability of the super capacitor. In addition, the preparation method is simple to operate, good in reproducibility and suitable for large-scale production. |
