A facile approach for the synthetic fabrication of iron oxide (Fe3O4) particles is presented and their potential application towards energy storage (as an electrode material within a supercapacitor) is explored. The Fe3O4 asymmetric supercapacitor is found to deliver a maximum specific capacitance of similar to 120 F g(-1) at a current density of 0.1 A g(-1) in an aqueous electrolyte solution (3M KOH) retaining 93.70% of its initial capacity over 1000 cycles. Additionally, an iron based hydrogen superoxide [ FeO(OH)] supercapacitor is readily fabricated and is found to exhibit a maximum specific capacitance of similar to 400 F g(-1) at a discharge current of 0.1 A g(-1) in a 3M KOH solution.
