Co3O4 has attracted more attentions as supercapacitor active materials due to its high theoretical specific capacitance (3560 F g-1),excellent reversibility,good electrical conductivity,long cycle life and environmental friendliness.1-3 In this report,three kinds of surfactants,sodium dodecyl sulfate (SDS),cetyltrimethylammonium bromide (CTAB) and polyvinyl pyrrolidone (PVP),are used in a typical hydrothermal process for controlling the morphology of the Co3O4 nanowire superstructure on Ni foam for high performance supercapacitors.
