Abstract
Nanoporous copper (NPC) with an average pore size of 5–500 nm was fabricated by dealloying Mn-Cu alloy under the help of hindering force of surfactants as well as promoting force of voltage. The microstructures of NPC were characterized through X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) analysis. The influence of alloy composition with Cu content from 15% to 45% on nanoporosity was systematically investigated in both chemical and electrochemical dealloying. It is found that alloy composition has a significant effect on the microstructure of NPC with a rapid growth of pore sizes as the Cu composition decrease.
