Gaseous CO₂ is transformed photochemically and thermochemically to CH₄ using visible and near-infrared photons over a catalyst comprising black silicon nanowire supported ruthenium. Experimental results suggest the photochemical effect is consequent of the comparatively small band gap of Si (E_g=1.1eV) compared to other supports such as silica and alumina (E_g>3eV).
