Electrophoretically-deposited nano-Fe3O4@carbon 3D structure on carbon fiber as high-performance supercapacitors

Structural and electrochemical behaviors of electrophortically-deposited Fe3O4 and Fe3O4@C nanoparticles on carbon fiber (CF) were investigated. The nanoparticles were synthesized via a green-assisted hydrothermal route. The as-prepared samples were characterized by x-ray diffraction, transmission a...
