Electrochemically shape-controlled synthesis of trapezohedral platinum nanocrystals with high electrocatalytic activity.
Trapezohedral Pt nanocrystals enclosed by 24 high-index {522} facets have been successfully prepared for the first time in high yield by a direct square wave electrodeposition method. They exhibit a significantly enhanced catalytic activity for C-1 molecules (CO, CH(3)OH, HCOOH).
