Shape matters : Platinum‐based alloy nanocrystals can be used as electrocatalysts that facilitate the oxidation and reduction reactions involved in a proton‐exchange membrane fuel cell (see picture). Recent work has demonstrated how the shape control of Pt–Mn alloy nanocrystals can result in increased activities when the alloys are used in fuel‐cell electrocatalysts.
