摘要
In this work, hierarchical core-shell hollow iron-cobalt sulfides nanoarrays supported on conductive nickel foam (Fe-Co-S/NF) were fabricated using metal-organic frameworks (MOFs) as the sacrificial templates. Delicately manipulating the etching/ion-exchange reaction between Co-MOF and FeSO4 and the subsequent solvothermal sulfurization led to the formation of hierarchical core-shell hollow nanostructure with FeCo2S4-nanosheets shell assembled on the Co3S4 hollow nanoarrays. Owing to the complex composition and unique structure, the obtained Fe-Co-S/NF possessed abundant electroactive sites, short charge/ion diffusion path, rich redox reactions and good structural robustness, contributing to the boosted electrochemical performance as supercapacitor electrodes. Consequently, the obtained FeCo-S/NF electrode exhibited a specific capacitance of 2695 F g(-1) at 1 A g(-1), a favorable rate capability with 69.8% capacitance retention at 10 A g(-1) (much higher than that of CoS/NF electrode, i.e., 36.3%), and a retention of 84% over 1000 cycles. Moreover, an asymmetric supercapacitor was assembled by engaging Fe-Co-S/NF and reduced graphene oxide (rGO) as cathode and anode, respectively. The obtained device delivered a high energy density of 43.6 W h kg(-1) at a power density of 770 W kg(-1), while maintaining a capacity retention of 89.6% after 5000 cycles. The robust electrochemical properties indicate that the FeCo-S/NF can be used as promising electrode materials for high performance supercapacitors applications. (C) 2019 Elsevier Ltd.
