Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Revealing the electronic structures of Pt‐alloys explains why the addition of transition metal to Pt speeds up the oxygen reduction reaction</bold>. It is found that transition metals in the subsurface induce charge polarization at the surface and suppresses the surface‐states. The modified surface‐states of Pt surface layer critically affects the chemical bonding between oxygen and Pt surfaces. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4t36x5kd" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
