Cutting edge : A Cu 2 O jagged polyhedron, with numerous {110} edges and {111} corners, has been developed through a top‐down selective oxidative etching process at the expense of the original {111} facet (see figure). The as‐prepared nanocrystals exhibited higher photocatalytic activities for the degradation of methylene orange, which may be primarily ascribed to the increased edges and corners.
