A novel hybrid BiVO₄–SiO₂ composites with mesoporous composite structure were synthesized by hydrothermal calcination method. The as-prepared BiVO₄/SiO₂ hybrid material was characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, UV–vis diffuse reflectance spectroscopy and BET measurements, respectively. Its photocatalytic activity was evaluated by the performance for decomposing C.I. Reactive Blue 19 in aqueous solution under visible light irradiation, and photocatalytic efficiency was effectively improved compared to the pure semiconductor materials.
