3O 4@Fe 2O 3 core-shell nanowire arrays electrode for supercapacitors]]>

摘要

AbstractHerein we demonstrate the rational design and fabricate of the Co3O4nanowire@Fe2O3nanorod core-shell nanowire arrays on carbon cloth for supercapacitor electrodes. When measured as electrode material for supercapacitors, the Co3O4@Fe2O3electrode delivers high areal capacitance of 245?mF/cm2at a current density of 1?mA/cm2. The excellent electrochemical performances of the Co3O4@Fe2O3electrode can be attributed to the unique core-shell nanoarchitecture and synergistic effect. The hydrothermally synthesized Co3O4nanowire arrays serve as the conductive scaffold for the growth of mesoporous Fe2O3nanorods, which facilitate fast charge transport throughout the whole electrode. These results indicate that the Co3O4@Fe2O3core-shell nanowire arrays are a promising electrode material for next-generation high-performance supercapacitors.Graphical abstractDisplay OmittedHighlights?The Co3O4@Fe2O3core-shell nanowire arrays have been fabricated for supercapacitors.?The Co3O4@Fe2O3electrode deliver a high areal capacitance of 245?mF/cm2.?The excellent performances due to the unique nanostructure and synergistic effect.]]>
