Abstract
We demonstrate a template-free synthetic approach for the preparation of a highly conductive Cu/Cu2O nanocomposite electrode by a chemical reduction process. Cu2O octahedra were prepared through chemical dehydrogenation of as-synthesized Cu(OH)2 nanowire precursors. To provide a sufficiently electron-conducting network, the Cu2O particles were transformed into Cu/Cu2O nanocomposites by an intentional reduction process. The Cu/Cu2O nanocomposite electrodes showed enhanced cycling performance compared to Cu2O particles. Furthermore, their rate capabilities were superior to those of their mechanically mixed Cu/Cu2O counterparts. This enhanced electrochemical performance of the hybrid Cu/Cu2O nanocomposites was ascribed to the formation of homogeneous nanostructures, offering an efficient electron-transport path provided by the presence of highly dispersed Cu nanoparticles.
