Synthesis of Mn^sub 3^O^sub 4^ nano-materials via CTAB/SDS vesicle templating for high performance supercapacitors

In this work, nano-structured Mn3O4 particles with spongy-morphology were synthesized through vesicle templating, where hexadecyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) were used as cationic-anionic surfactants. The Mn3O4 electrode materials exhibited a high specific capaci...

Summary:In this work, nano-structured Mn3O4 particles with spongy-morphology were synthesized through vesicle templating, where hexadecyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) were used as cationic-anionic surfactants. The Mn3O4 electrode materials exhibited a high specific capacitance (451 F g-1) at a current density of 0.5 A g-1 in 1 mol L-1 Na2SO4 electrolyte, and retained 333 F g-1 when the current density was increased to 5 A g-1. Its capacitance retention is also high (up to 92%) after 10,000 cycles at a current density of 5 A g-1.
