Abstract

Nanoporous filters are used in a variety of applications, ranging from sensing, catalysis, purification and separation devices to medicine. In this study attempts were made to obtain nanoporous copper from brass via dealloying process. This involved leaching of the alloy in NaOH solution. Experiments on cold-rolled and annealed brass have shown that while a porous surface layer can be obtained, it is difficult to obtain a full porous structure across the full thickness of the sheet.
