Crystal clear : Uniform Cu 2 O nanooctahedra ( o ‐Cu 2 O) and nanocubes ( c ‐Cu 2 O) undergo surface restructuring during CO oxidation for the in‐situ formation of catalytically active CuO thin films to give CuO/ o ‐Cu 2 O and CuO/ c ‐Cu 2 O, respectively (see picture). The structure and catalytic performance of CuO thin films are controlled by the crystal plane exposed on the underlying Cu 2 O nanocrystals.
