Description

In this project, carbon encapsulated Fe${}_3$O${}_4$ for supercapacitors electrode was synthesized using Fe${}_3$(No${}_3$)${}_3$ 9H${}_2$O and C${}_6$H${}_1{}_2$O${}_6$ as precursors and NaCl as supporting material. The mixture was annealed at 700 ${}^{\circ}$C, 720 ${}^{\circ}$C, 750 ${}^{\circ}$C and 770 ${}^{\circ}$C in argon atmosphere for 2 hours and heated at 250 ${}^{\circ}$C in air for 6 hours. The results showed that the supercapacitors with carbon encapsulated Fe${}_3$O${}_4$ had the maximum specific capacitance of 48.5 F/g in 1 M of Na${}_2$SO${}_4$ aqueous electrolyte. This could be attributed to a good electrical conductivity of carbon and the promotion of redox reaction in Fe${}_3$O${}_4$.
