- •
Size and composition of nanoporous layers tailored in de-alloying Au-based glassy ribbons.
- •
From amorphous precursor fine crystals occur in ligaments with residual Pd and Ag.
- •
Fully de-alloyed ribbons most active towards methanol electro-oxidation.
- •
Electrocatalytic efficiency is 60% after 500cycles and for repetitive experiments.
