A series of bi-continuous and uniform nanoporous structures were fabricated successfully through chemical dealloying from quaternary Zr65Cu17.5Fe10Al7.5 amorphous ribbons in hydrofluoric acid (HF) solutions under a free corrosion condition. Nanoporous structures obtained from dealloying amorphous ribbons for 5 h in 0.02 M,0.035 M and 0.05 M HF solutions have mean pore sizes of 30–40 nm. A three-dimensional...
