With the increasing energy crisis and environmental pollution problems, development of solar-powered photocatalytic technologies for green efficient removal emerging pollutants from aquatic ecosystems has become an urgent need. Bismuth niobate (Bi3NbO7), as a bismuth-based photocatalyst, attracted much attention due to its unique electronic structure optical properties. However, Bi3NbO7 synthesized by traditional hydrothermal method suffers problems large size, limited active sites, harsh preparation conditions, which severely limit performance. In this study, small-sized nanoparticles (BNO-Ov-3) enriched with oxygen vacancies were successfully one-step solvothermal using ethylene glycol solvent structure-directing agent. Glycol not only inhibited grain growth reduced size micrometers nanometers, but also promoted formation through reducing property. Compared conventional method, BNO-Ov-3 enhanced degradation rate tetracycline hydrochloride (TC) 49.8% 92.1% under visible light irradiation. The mechanism performance enhancement was revealed XPS, EPR, PL characterization: synergistic effect nanosize effectively photogenerated carrier complexation charge separation transfer. This study provides strategy controlled synthesis bismuth lays theoretical foundation application in photocatalysis.
