The Front Cover shows a strategy for the synthesis of Pd@Pt3–4L octahedral nanocrystals with a clean surface and supported on carbon. The bottom of the image shows transmission electron microscopy (TEM) and high-angle annular dark-field scanning TEM images of the octahedral Pd@Pt3–4L support on carbon.In their Full Paper, S. Bao et al. demonstrate that by dispersing Pd octahedral seeds on a carbon black support, Pt ultrathin shells can be conformally deposited on the seeds in a layer-by-layer fashion without involving any capping agent or stabilizer. The as-obtained catalyst exhibited a greatly enhanced specific activity relative to a reference sample prepared in the presence of a polymer stabilizer and a commercial Pt/C catalyst. More information can be found in the Full Paper by S. Bao et al. on page 414 in Issue 3, 2017 (DOI: 10.1002/cctc.201601438).
