One-dimensional iron hydroxide@cadmium hydroxide nanostructures were prepared, showing core-shell architecture for electrochemical supercapacitive electrode design. The electrode exhibited high specific capacitance at a specific current density and retained 52% of its initial capacity after 5000 cycles.
One-dimensional iron hydroxide@cadmium hydroxide nanostructures have been prepared by sequentially converting cadmium hydroxide into iron hydroxide via simple and cost-effective cation exchange reaction based on solubility product to design electrochemical supercapacitive electrode. Surface architecture of iron hydroxide@cadmium hydroxide nanostructures in the form of core-shell enables easy and effective electrochemical reactions which have been studied via electrochemical cyclic voltammetry and charge-discharge studies. Interestingly, iron hydroxide@cadmium hydroxide electrode exhibits specific capacitance of 368 F g(-1) at current density of 0.5 A g(-1) along with electrochemical impedance analysis. Capacitance retention performed at the scan rate of 50 mV s(-1) for 5000 cycles results in 52% capacity of its initial.
