Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Binary co‐catalysts</bold> of Pt and Cu₂O with a core–shell structure significantly enhance the photocatalytic reduction of CO₂ with H₂O to CH₄ and CO. The Cu₂O shell provides sites for the preferential activation and conversion of CO₂, whereas the Pt core extracts the photogenerated electrons from TiO₂. The deposition of Cu₂O shell on Pt nanoparticles markedly suppresses the reduction of H₂O to H₂ (see picture).<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg20p48zgt" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
