摘要：

The photoreduction of CO₂ to CO offers a promising sustainable and clean approach for a global newenergy program. Coupling this reductive process with a matched water photo-oxidation pathway is anattractive avenue to accelerate the half-reaction of CO₂ reduction. Herein, we propose a threecomponent photocatalyst design strategy for reducing CO₂ to CO coupled with water oxidation viaa two-electron/two-step pathway. Employing polyoxotitanium ([Ti₁₇O₂₄(OPrⁱ)₂₀]) as a titanium source,ultra**all TiO_2-x nanoparticles coated with ultrathin carbon layers (C-TiO_2-x) were fabricated andloaded on to a g-C₃N₄ matrix through chemical bonding (C-TiO_2-x@g-C₃N₄) for the first time. The

optimized C-TiO_2-x@g-C₃N₄ photocatalyst showed a very high activity of 12.30 mmol g^-1 (204.96 mmolg_TiO2^-1) CO generation within 60 h visible-light irradiation, which represents the highest CO productionrate to date among the reported TiO₂-based materials under similar conditions. The excellent adsorptioncapability of C-TiO_2-x@g-C₃N₄ for photons, H⁺ protons, and CO₂ molecules together with efficientcharge separation and the two-electron/two-step oxidative pathway lead to the high reactivity.
