Direct growth of Fe₂V₄O₁₃ nanoribbons on a stainless-steel mesh for visible-light photoreduction of CO₂ into renewable hydrocarbon fuel and degradation of gaseous isopropyl alcohol

One-dimensional Fe₂V₄O₁₃ nanoribbons 10-20 μm long and 20-30 nm thick growing directly on a stainless-steel mesh (SSM) have been successfully obtained by a simple and facile hydrothermal reaction without any templates or surfactants. The SSM served as not only the Fe source but also the substrate for the deposition of vanadium and oxide elements. The Fe₂V₄O₁₃ nanoribbon as an easily reused photocatalyst shows great potential for the efficient photoreduction of CO ₂ into renewable hydrocarbon fuel (CH₄) and for the removal of organics from air under visible-light illumination.
