Photomethanation of Gaseous CO(2) over Ru/Silicon Nanowire Catalysts with Visible and Near‐Infrared Photons

Gaseous CO(2) is transformed photochemically and thermochemically in the presence of H(2) to CH(4) 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. Thes...

Sumario:Gaseous CO(2) is transformed photochemically and thermochemically in the presence of H(2) to CH(4) 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) CO(2) capture, ii) gaseous water splitting into H(2), and iii) reduction of gaseous CO2 by H(2).
