| Abstract: | Mixed‐metal sulfide Zn1?xMnxS nanorod‐assembled hierarchical hollow spheres were synthesized by a template‐free solvothermal process based on Ostwald ripening. In the reaction system, glycerol plays a key role in the formation of ZnxMn1?xS hierarchical hollow structures by a quasi‐microemulsion‐template mechanism. When applied as capacitor electrode material, the hierarchical Zn1?xMnxS hollow spheres show excellent electrochemical performance. Specifically, Zn0.25Mn0.75S hollow spheres can deliver a high specific capacitance of 664 F g?1 at a current rate of 1 A g?1, which is almost five times of that of MnS under the same conditions and higher than those of previously reported single Mn‐based compounds. |
