The solar-driven photocatalytic reduction of CO2 into fuels using a C3N4-based photocatalyst has shown great application potential in addressing challenges related to energy and emission. However, this process suffers from severe charge recombination sluggish H2O oxidation kinetics, resulting low efficiency. In study, 2D/2D S-scheme heterojunction by combining oxygen vacancy-rich BiVO4 nanoflakes with C3N4 nanosheets (denoted as Ov-BVO/CN) was fabricated mitigate the aforementioned issues, where serves water booster center. By leveraging synergistic effects lamellar morphology an charge-transfer pathway, Ov-BVO/CN achieves efficient separation while maintaining maximized redox capabilities. Moreover, theoretical calculations demonstrated that Ov on surface reverses rate-limiting step reducing its barrier, thereby accelerating reaction kinetics. optimized demonstrates remarkably improved evolution rates for CO (13.8 μmol g–1 h–1) CH4 (5.9 h–1), which are approximately 3.8 3.5 times higher than those CN under visible-light irradiation, respectively. This work highlights design fabrication highly heterostructure photocatalysts photoreduction.
