Abstract
In this paper, nanoporous copper (NPC) was prepared by chemical dealloying of the Al70Cu30 (at.%) melt-spun alloy. The dealloying of Al70Cu30 in 4.2 vol% HCl solution facilitates the bilayer NPC with various morphology. The results show that the formation of pores is simultaneously controlled by the dissolution of Al and the diffusion of Cu atoms in the alloy/electrolyte interface. In particular, the NPC presents a bimodal pore size distribution: larger pores with size of 25–50 nm and smaller pores with size of 3–4 nm. The specific surface area of the NPC is determined as 25.24 ± 0.08 m2 g−1 through N2 adsorption/desorption experiment and Brunauer–Emmett–Teller (BET) analysis. Such high porosity and surface-area-to-volume ratio of the NPC reveal its potential application in catalysts, sensors, actuators, fuel cells, etc.
