Abstract

We report the synthesis of citrate stabilized iron oxide (C-Fe₃O₄) spherical nanoparticles for supercapacitor electrodes. The citrate functional group present in the surface of the Fe₃O₄ nanoparticles effectively controls the morphology and the surface area of the nanostructures. The C-Fe₃O₄ electrodes exhibited a battery-like energy storage properties with a maximum specific capacity of 146 Cg⁻¹ (242 Fg⁻¹) which is much higher than the specific capacity of citrate free Fe₃O₄ electrode (62 Cg⁻¹; 112 Fg⁻¹). Moreover, the C-Fe₃O₄ electrode showed better cyclic stability (75%) than the citrate free Fe₃O₄ electrode (~35%) after 1000 charge/discharge cycles.
