Description
Summary:Integration of 1D, core/shell, and jagged features into one entity may provide a promising avenue for further enhancing catalyst performance. However, designing such unique nanostructures is extremely challenging. Herein, 1D serrated Au/Pd core/shell nanowires (CSNWs) with jagged edges were produced simply by a one‐pot, dual‐capping‐agent‐assisted method involving co‐reduction, galvanic replacement, directional coalescence of preformed nanoparticles, and site‐selective epitaxial growth of Pd. Au/PdCSNWs, compared with the commercially available Pd/C, exhibited enhanced electrocatalytic performance towards liquid fuel oxidation because of the synergistic effect of the electronic structure and low‐coordinated jagged edges. Rough around the edges: Serrated Au/Pd core/shell nanowires with jagged edges integrate core/shell, one‐dimensional, and jagged features within one single entity, and exhibit superior electrocatalytic activity towards ethanol and formic acid oxidation.
