摘要
Catalytic cobblestones: Monodisperse platinum nanoparticles were prepared with controlled sizes (3-7 nm) and shapes (polyhedron, truncated cube, or cube). The cubic nanoparticles are a much more active cathode catalyst for the oxygen reduction reaction: the current density J from 7 nm cubes is four times that of the other shapes (see picture), indicating great potential for fuel cell applications.
