A new multi-step synthesis method, including thermo-plastic forming and electro-chemical processing, is proposed to fabricating different nano-scale morphologies of Ni60Pd20P17B3 bulk metallic glass. Due to the large surface area and the enrichment of the active noble metal on the surface, these processed metallic glass morphologies show enhanced catalytic behavior during methanol oxidation. Also, these nanostructures show less accumulation of poisoning intermediates on the catalysis surface.
