Simple synthesis of Fe۳O۴@Fe۳S۴ Nanocomposites coated with polyindole-polythiophene for high-performance supercapacitor

To prevent a major energy crisis in the near future, it is necessary to assemble efficient electrochemical energy storage devices such as supercapacitors. Herein, a Fe۳O۴@Fe۳S۴ nanocomposites coated with polyindole-polythiophene on nickel foam (NF) has been prepared by following a low facile, multistep method. In terms of structural and electrochemical performance, the nanocomposites have been investigated. The electrochemical properties of as fabricated Fe۳O۴@Fe۳S۴@PIn-PTh are studied in ۲M KOH. A specific capacitance of ۱۰۰.۸۳ F g-۱ at a current density of ۲ A g-۱. The results of the synthesized sample in comparison with Fe۳O۴ show that using sulfide metal and polymer component improve the electrochemical performance. These characteristics of Fe۳O۴@Fe۳S۴@PIn-PTh as the active material illustrate a sutiable performance as a cathode material for electrochemical energy storage.To prevent a major energy crisis in the near future, it is necessary to assemble efficient electrochemical energy storage devices such as supercapacitors.
