Abstract
Metal nanotubes are provided comprising a composition having formula (M)NT: wherein M=Pt, Pd, or Au; wherein the nanotubes have: a wall thickness of from 2 to 12 nm; an outer diameter of from 30 to 100 nm; and a length of from 5 to 30 μm. Metal nanowires are also provided comprising a composition having formula (M)NW: wherein M=Ag or Cu; wherein when M=Ag, the nanowires have a diameter of from 25 to 60 nm and a length of from 1 to 10 μm; and when M=Cu, the nanowires have a diameter of from 50 to 100 nm and a length of from 10 to 50 μm. In other embodiments, fuel cells are also described having at least one anode; at least one cathode; an electrolyte membrane between the at least one anode and at least one cathode; and a catalyst comprising either of the above described metal nanotubes or nanowires.
