Shape‐dependent nanocatalysis : Monodisperse cubic, rhombic dodecahedral, and octadecahedral Cu 2 O nanocrystals (NCs) were selectively synthesized. Cu 2 O octadecahedra exhibited the best activity upon recycling, though etched on nanoframes, in the ligand‐free oxidative arylation of phenylacetylene. Rhombic dodecahedra had moderate activity and optimal stability, whereas cubes suffered significant loss of activity during recycling.
