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.
