Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201404426-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Direct growth of multigrain platinum nanowires</bold> on sulfur‐doped graphene (PtNW/SG) is reported. The growth mechanism, including Pt nanoparticle nucleation on SG, followed by nanoparticle attachment with orientation along the &lt;111&gt; direction is highlighted. PtNW/SG demonstrates improved Pt mass and specific activity compared with commercial catalysts toward oxygen reduction, in addition to dramatically improved stability through accelerated durability testing. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh3w99kjws" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
