Abstract
- In this letter, Fe 3 O 4 ultra-fine nanoparticles are prepared through PEG-assisted cathodic electrosynthesis from ethanol media. The XRD, FE-SEM, TEM and BET data confirmed the pure phase (i.e. magnetite), fine particle size (∼5 nm) and high surface (176.7 m 2 /g) of the electro-synthesized product. The electrochemical evaluations through cyclic voltammetry (CV) and continuous charge-discharge (GCD) techniques proved that the prepared Fe 3 O 4 nanoparticles have excellent capacitive storage as high as 218.3 F g −1 and stable cycling performance of 4.7% decay after 2000 cycling at 0.5 A g −1 . Furthermore, this work provides a facile electrochemical procedure to fabricate high performance iron oxide electrode for use in supercapacitors. [ABSTRACT FROM AUTHOR]
