摘要：
Iron cobaltite (FeCo2O4) has been successfully prepared via a conventional facile solvothermal reaction, followed by a calcination step. The as-prepared material exhibits a 2D-nanosheets morphology, which expected to provide better electronic transportation as compared to zero-dimensional nanomaterials. FeCo2O4 nanosheets were tested as an electrode material for supercapacitor applications. The as prepared material showed an excellent electrochemical performance on Ni foam substrate. It exhibited high charge storage property with a specific capacitance value of 853.8 F g(-1) at 5 A g(-1) and also a remarkable cycling stability with 87.5% capacitance retention being stable after 3000 cycles. It also showed a superior rate capability with (73%) from 5 to 25 A g(-1). The excellent electrochemical performance of FeCo2O4 nanosheets is related to its high conductivity, high porosity, and the fast electrons ions transportation. (C) 2017 Elsevier Inc.
