Preparation of Sandwich-like NiCo(2)O(4)/rGO/NiO Heterostructure on Nickel Foam for High-Performance Supercapacitor Electrodes

ABSTRACT: A kind of sandwich-like NiCo(2)O(4)/rGO/NiO heterostructure composite has been successfully anchored on nickel foam substrate via a three-step hydrothermal method with successive annealing treatment. The smart combination of NiCo(2)O(4), reduced graphene oxide (rGO), and NiO nanostructure...

description ABSTRACT: A kind of sandwich-like NiCo(2)O(4)/rGO/NiO heterostructure composite has been successfully anchored on nickel foam substrate via a three-step hydrothermal method with successive annealing treatment. The smart combination of NiCo(2)O(4), reduced graphene oxide (rGO), and NiO nanostructure in the sandwich-like nano architecture shows a promising synergistic effect for supercapacitors with greatly enhanced electrochemical performance. For serving as supercapacitor electrode, the NiCo(2)O(4)/rGO/NiO heterostructure materials exhibit remarkable specific capacitance of 2644 mF cm(−2) at current density of 1 mA cm(−2), and excellent capacitance retentions of 97.5% after 3000 cycles. It is expected that the present heterostructure will be a promising electrode material for high-performance supercapacitors. GRAPHICAL ABSTRACT: [Image: see text]
