Assembly of Pt Nanowires into Cubelike Superstructures Supported on Aligned Carbon Nanotubes as Highly Stable Electrocatalysts

Go nano! Cubelike Pt nanowire superstructures supported on vertically aligned bamboo-shaped carbon nanotubes (see the FESEM image) are used as electrocatalysts for fuel cells. They exhibit remarkably improved stability over the commercial Pt/C catalyst made of Pt nanoparticles on amorphous carbon.
