Mn3O4/worm-like mesoporous carbon synthesized via a microwave method for supercapacitors
Source abstract
Abstract
A quick and facile microwave method has been employed to prepare Mn3O4/worm-like mesoporous carbon (Mn3O4–MC) composites. Structural and morphological characterizations of worm-like mesoporous carbon and Mn3O4–MC composites have been carried out using X-ray diffraction, transmission electron microscopy, N2 adsorption–desorption, and electrochemical measurement. Cyclic voltammograms demonstrate that the Mn3O4–MC composites perform improved capacitive behavior at the range of −0.8~0.2 V (vs. Hg/HgO electrode) with reversibility. The Mn3O4–MC composite electrode possesses an enhanced specific capacitance of 266 F g−1 at a sweep rate of 1 mV s−1.
