The Front Cover shows the porous dendrite structure of CuC x –Cu and NiC x Ni that can be used as cost‐efficient bi‐functional catalysts instead of Pt and RuO 2 catalysts in Zn–air batteries. Although many research efforts have been devoted to developing alternative electrocatalysts to noble‐metal catalysts, the obtained catalysts are only highly active for either the oxygen reduction reaction (ORR) or the oxygen evolution reaction (OER). By introducing a stable metal‐carbide layer on a dendritic metal structure, we managed to prepare a catalyst with a high catalytic surface and an appropriate oxygen binding energy that can be use as bifunctional catalyst in Zn–air batteries. More information can be found in the Communication by Kim et al. on page 4203 in Issue 24, 2018 (DOI: 10.1002/cssc.201802122).
