Abstract
The article focuses on the fabrication of nano-porous copper and silver surfaces through selective anodic dissolution of uniform γ-phase Cu₅Zn₈ and Ag₅Zn₈ zinc coatings prepared by thermal diffusion plating in molten eutectic salts at 370°C. Electrochemical dealloying was conducted in a deep eutectic solvent composed of choline chloride and urea with added ZnCl₂ at 133°C, producing bi-continuous nano-porous structures with pore sizes around 100 nm on both metals. This method offers a controlled intermediate-temperature alternative to aqueous or molten salt electrolytes for surface engineering, with potential applications in sensors and catalysis due to the high surface area and pore morphology achieved.
