Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Au@Pd core–shell nanobricks (CNBs) with concave surfaces and Pd shells with a thickness of approximately 5 nm were synthesized by co‐reduction of HAuCl₄ and H₂PdCl₄ in the presence of Au seeds and Ag ions. These as‐synthesized concave CNBs exhibit significantly enhanced catalytic activity for the electrooxidation of ethanol in alkaline media compared to the commercially‐used Pd black. The improved performance of the Au@Pd CNBs can be attributed to the exposed stepped surfaces, high‐index facets, and the synergistic effects of the core and shell metals.</p> </abstract>
