BiVO₄ microsheets with particle size of 1~2 μm were fabricated by hydrothermal method. Then, Ag₂CO₃/BiVO₄ composite microsheet photocatalysts with different contents of Ag₂CO₃ were synthesized via precipitation method. The products were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform-infrared (FTIR) spectroscopy, UV-Vis diffuse reflectance spectroscopy (DRS), photoluminescence (PL) emission spectroscopy, transient photocurrent-time response. The photocatalytic activity of the samples were evaluated by photocatalytic degradation of rhodamine B under visible light irradiation. The results showed that loading of Ag₂CO₃ was beneficial to improve the specific surface area and surface properties of the catalyst. Activity test indicated that BiVO₄ loaded with optimal 10%(w/w) Ag₂CO₃ resulted in 4.4 times increase in activity with respect to BiVO₄ under visible light illumination. The results of photoluminescence (PL) emission spectroscopy and transient photocurrent-time response showed that the coupled Ag₂CO₃ can effectively inhibit the recombination of photogenerated electrons and holes. Active radicals trapping experiments indicated that hole and hydroxyl radicals were the reactive oxygen species in this Ag₂CO₃/BiVO₄ system. The enhancement in activity of Ag₂CO₃/BiVO₄ could be attributed to the heterojunction structure formed by Ag₂CO₃ with wider band gap and BiVO₄ with narrower band gap. This heterojunction effectively restrained the recombination of photogenerated electrons and holes. Moreover, the suitable energy band structure brought about strong oxidation ability due to more holes were produced.
