A Highly Durable Platinum Nanocatalyst for Proton Exchange Membrane Fuel Cells: Multiarmed Starlike Nanowire Single Crystal

A new “star” catalyst: Carbon-supported multiarmed starlike Pt nanowires (see SEM picture) are highly active and stable electrocatalysts for proton-exchange membrane fuel cells. This novel nanostructure shows much improved activity and durability over the current commercial Pt/C catalyst made of Pt nanoparticles.
