Synchronized conversion of CO2 and H2O into hydrocarbons oxygen via infrared-ignited photocatalysis remains a challenge. Herein, the hydroxyl-coordinated single-site Ru is anchored precisely on metallic TiN surface by NaBH4/NaOH reforming method to construct an infrared-responsive HO-Ru/TiN photocatalyst. Aberration-corrected high-angle annular dark-field scanning transmission electron microscopy (ac-HAADF-STEM) X-ray absorption spectroscopy (XAS) confirm atomic distribution species. XAS density functional theory (DFT) calculations unveil formation HO-RuN5-Ti Lewis pair sites, which achieves efficient polarization/activation dual coordination with C O atoms HO-Ru/TiN. Also, implanting species powerfully boosts separation transfer photoinduced charges. Under infrared irradiation, catalyst shows superior CO2-to-CO transformation activity coupled oxidation release O2, reduction rate can further be promoted about 3-fold under simulated sunlight. With key reaction intermediates determined in situ diffuse reflectance Fourier transform (DRIFTS) predicted DFT simulations, possible photoredox mechanism system proposed.

Abstract Metal sulfide‐based homojunction photocatalysts are extensively explored with improved photocatalytic performance. However, the construction of metal S‐scheme remains a challenge. Herein, fabrication 2D CdIn 2 S 4 nanosheets coated 3D octahedra (referred to as 2D/3D n‐CIS/o‐CIS) photocatalyst is reported by simply adjustment polyvinyl pyrrolidone amount during solvothermal synthesis. The formation within n‐CIS/o‐CIS systematically investigated via series characterizations, which can generate an internal electric field facilitate separation and migration photogenerated electron‐hole pairs. composite exhibits significantly activity stability in selective oxidation phenylcarbinol (PhCH OH) benzaldehyde (PhCHO) when compared pure n‐CIS o‐CIS samples under visible light irradiation. It hoped that this work contribute novel insights into development sulfides for solar energy conversion.

The use of photocatalytic solar energy to drive CO2 reduction is beneficial for addressing fossil fuel shortages and environmental pollution issues. We synthesized a twin S-scheme g-C3N4/CuFe2O4/ZnIn2S4 heterojunction, which was used construct self-supporting three-phase system reduction. Two built-in electric fields in this heterojunction induced effective migration photogenerated carriers, resulting wide light response range strong oxidation ability. This without sacrificial agent had high CH4 selectivity (96.8%) surprise production rate (267.4 μmol g–1 h–1), still maintained an excellent cycle (249–267.4 h–1) during five cycles. In addition, possessed both hydrophilicity hydrophobicity, achieved efficient transformation into by controlling interface wettability. g-C3N4 as hydrophobic layer promoted mass transfer achieve the enrichment on surface; ZnIn2S4 hydrophilic could well adsorb H2O, further oxidized holes many protons (H+). Finally, DFT calculations found that Fe–N bonds located between CuFe2O4 played crucial role They served bridge electron induce bending adsorption CO2, enhanced *CO stabilization *H.
