Abstract: The monolithic hierarchical structured nanoporous copper ribbons (HSNCRs) have been facilely fabricated by one-pot chemical dealloying of dual-phase Al 27. at.% Cu alloy with hypereutectic structure. The results show that dealloying solution has a key influence on fabrication, microstructure and porosity of products. The HSNCRs are composed of interconnected large-sized maze/river-shape channels with laminated/uniform porous channel walls upon dealloying in acidic/alkaline medium. The specific surface area of samples by dealloying in alkaline solution is two times larger than that in acidic solution. Additionally, microstructure (morphology, sizes and distribution) and porosity of products can be tuned effectively by changing dealloying solution.
