title: Photomethanation of Gaseous CO2over Ru/Silicon Nanowire Catalysts with Visible and Near-Infrared Photons.
abstract: Gaseous CO2is transformed photochemically and thermochemicallyin the presence of H2to CH4at 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) CO2capture, ii) gaseous water splitting into H2, and iii) reduction of gaseous CO2 by H2.
