Crystal-Plane-Controlled Surface Restructuring and Catalytic Performance of Oxide Nanocrystals

Crystal-Plane-Controlled Surface Restructuring and Catalytic Performance of Oxide Nanocrystals

Crystal clear: Uniform Cu2O nanooctahedra (o‐Cu2O) and nanocubes (c‐Cu2O) undergo surface restructuring during CO oxidation for the in‐situ formation of catalytically active CuO thin films to give CuO/o‐Cu2O and CuO/c‐Cu2O, respectively (see picture). The structure and catalytic performance of CuO t...

Zusammenfassung:Crystal clear: Uniform Cu2O nanooctahedra (o‐Cu2O) and nanocubes (c‐Cu2O) undergo surface restructuring during CO oxidation for the in‐situ formation of catalytically active CuO thin films to give CuO/o‐Cu2O and CuO/c‐Cu2O, respectively (see picture). The structure and catalytic performance of CuO thin films are controlled by the crystal plane exposed on the underlying Cu2O nanocrystals.
