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 .
