Temperature-controlled growth of single-crystal Pt nanowire arrays for high performance catalyst electrodes in polymer electrolyte fuel cells

- The synthesis temperature plays a key role on the growth behavior of Pt nanowires on carbon paper support.
- An optimal temperature of 40 °C to grow uniform Pt nanowire arrays on large area support.
- Pt nanowire gas diffusion electrode with excellent activity and durability achieved.
- A possible mechanism suggested for the role of temperature in Pt nanowire growth.
