Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aenm201400057-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A conceptual metallic/semiconducting TaB₂/Ta₂O₅ core/shell heterostructure</bold> exhibits a substantial improvement in photocatalytic hydrogen evolution rate under both UV and visible light. TaB₂ plays a dual role in boosting the photocatalytic activity by extending the light‐absorption range via efficient interfacial electronic modification and by promoting the separation and transfer of photoexcited charge carriers by using metallic TaB₂ core as an electron collector. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh12v7dp1k" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
