Shape-controlled catalysis: High-quality Pt–Cu nanocubes with an average size of about 8?nm (see picture, scale bar=20?nm) were synthesized from a high-temperature organic solution system in the presence of various capping ligands. These cubic Pt–Cu nanocrystals terminated with {100} facets demonstrated a superior catalytic activity towards methanol oxidation compared to similar sized Pt–Cu and Pt nanospheres.
