| Abstract: A novel Ag/Ag2MoO4/Bi2MoO6 ternary photocatalyst was successfully prepared by hydrothermal, chemical deposition and in-situ photoreduction process. The as-prepared photocatalysts were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS) and UV-visible diffuse reflection spectroscopy (UV-Vis DRS) to investigate the composition, morphology, optical absorption characteristics and photoelectrochemical properties. The photocatalytic performance of Ag/Ag2MoO4/Bi2MoO6 photocatalyst was evaluated with tetracycline as the target pollutant under visible light. The research results show that, compared with pure Ag2MoO4 and Bi2MoO6, the surface plasmon resonance (SPR) effect of Ag significantly broadens the visible light absorption capacity and response range of the catalytic system. When the theoretical loading (mass fraction) of Ag2MoO4 was 24.6%, Ag/Ag2MoO4/Bi2MoO6 ternary photocatalyst could completely degrade tetracycline within 20 min, and maintained high catalytic activity after 5 cycles of use, showing good cycle stability. |
