The limited redox capability of photocatalysts often leads to harmful NO₂ byproduct formation during photocatalytic NO oxidation. Herein, Bi₄Ti₃O₁₂ nanosheets modified with plasmonic metallic bismuth and abundant oxygen vacancies were synthesized via an in-situ reduction method. The optimized catalyst (BTOR2, with a molar ratio of 40% NaBH₄ to Bi₄Ti₃O₁₂) achieved a maximum NO removal efficiency of 62.3%, significantly higher than pristine Bi₄Ti₃O₁₂ (40.5%) while minimizing NO₂ production. The results reveal that the synergistic effects of Bi's plasmonic resonance and oxygen vacancies enhanced visible light absorption and charge separation. The density functional theory (DFT) analysis showed electrons can transfer from Bi₄Ti₃O₁₂ to Bi, promoting O₂ activation to ^•O₂^- radicals. In-situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) confirmed that light-induced H₂O adsorption was strengthened, improving ^•OH radical generation. These radicals promoted the selective conversion of activated NO^- to NO₃^-, rather than NO₂. This work provides valuable insights for advancing research into efficient photocatalysts for air pollution control.
