Abstract

<abstract abstract-type="graphical" xml:lang="en" id="advs201400001-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Gaseous CO₂ is transformed photochemically and thermochemically</bold> in the presence of H₂ to CH₄ at millimole per hour per gram of catalyst conversion rates, using visible and near‐infrared photons. The catalyst used to drive this reaction comprises black silicon nanowire supported ruthenium. These results represent a step towards engineering broadband solar fuels tandem photothermal reactors that enable a three‐step process involving i) CO₂ capture, ii) gaseous water splitting into H₂, and iii) reduction of gaseous CO2 by H₂. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh31p052ws" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
