This is the first paper to report a series of bismuth oxyfluoride/bismuth oxyiodide/graphene oxide (BiO_mF_n/BiO_xI_y/GO) nanocomposites with different GO contents that were synthesized through a simple hydrothermal method and characterized using X-ray diffraction, transmission electron microscopy, scanning electron microscopy–energy dispersive spectroscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, Brunauer-Emmett-Teller specific surface areas, and UV–vis diffuse reflectance spectroscopy. The BiO_mF_n/BiO_xI_y/GO composites exhibited excellent photocatalytic activities in the degradation of crystal violet (CV) and 2-hydroxybenzoic acid (HBA) under visible-light irradiation. The order of rate constants appears to be Bi₅₀O₅₉F₃₂/BiOI/GO > BiOF/BiOI/GO > BiOI > Bi₅₀O₅₉F₃₂/BiOI/Bi₅O₇I/GO > BiOF > GO. The photocatalytic activity of Bi₅₀O₅₉F₃₂/BiOI/GO composites reached a maximum rate constant of 0.2539 h⁻¹, which is 1.1 times higher than that of Bi₅₀O₅₉F₃₂/BiOI and 1.3 and 110 times higher than those of BiOI and Bi₅₀O₅₉F₃₂, respectively.
