Core–Shell Structuring of Pure Metallic Aerogels towards Highly Efficient Platinum Utilization for the Oxygen Reduction Reaction
Abstract
<jats:title>Abstract</jats:title><jats:p>The development of core–shell structures remains a fundamental challenge for pure metallic aerogels. Here we report the synthesis of Pd<jats:sub><jats:italic>x</jats:italic></jats:sub>Au‐Pt core–shell aerogels composed of an ultrathin Pt shell and a composition‐tunable Pd<jats:sub><jats:italic>x</jats:italic></jats:sub>Au alloy core. The universality of this strategy ensures the extension of core compositions to Pd transition‐metal alloys. The core–shell aerogels exhibited largely improved Pt utilization efficiencies for the oxygen reduction reaction and their activities show a volcano‐type relationship as a function of the lattice parameter of the core substrate. The maximum mass and specific activities are 5.25 A mg<jats:sub>Pt</jats:sub><jats:sup>−1</jats:sup> and 2.53 mA cm<jats:sup>−2</jats:sup>, which are 18.7 and 4.1 times higher than those of Pt/C, respectively, demonstrating the superiority of the core–shell metallic aerogels. The proposed core‐based activity descriptor provides a new possible strategy for the design of future core–shell electrocatalysts.</jats:p>
