Electrodeposition was used to fabricate metallic CoNiCu and Cu nanotubes in polycarbonate membranes. The tubes were obtained from a low-efficiency CoNiCu electrolyte, critical to the evolution of tube formation. Tube wall thickness was assessed and alloy tubes filled with Cu metal demonstrated. A high-efficiency electrolyte was used to show the importance of the side reaction on the nanotube formation. Nanowires were obtained in the high-efficiency electrolyte while nanotubes were generated
