چکیده انگلیسی
A type of porous ZnFe2O4 (ZFO) was prepared by a template-assisted method. The ZFO precursor solution was impregnated into the hard-template polystyrene (PS) microspheres. The porous ZFO sample was obtained after the removal of PS microspheres template by calcination in air. The results indicate that the ZFO sample is successfully prepared and exhibits a porous structure. Electrochemical tests show that the specific capacitance of the porous ZFO is 301.8Â FÂ gâ1 at the scan rate of 2Â mVÂ sâ1 in 6Â M KOH aqueous electrolyte. In addition, the porous ZFO sample displays an excellent cycling stability in 6Â M KOH aqueous electrolyte. Nearly 140.97% of its initial capacitance can be observed after 5000 cycles when the cycling current density is 2Â AÂ gâ1.
