| description | Bismuth vanadate (BiVO<sub>4</sub>) has been investigated as a photocatalyst of great interest due to its ability to harvest photons efficiently in the visible spectral region. In addition, powdered BiVO<sub>4</sub> shows high photochemical stability, good dispersibility, and resistance to corrosion in oxidative conditions. Herein, we report the synthesis of monoclinic or tetragonal BiVO<sub>4</sub> particles using different methods, as well as the synthesis of hybrids materials through the combination of cobalt ferrite (CoFe<sub>2</sub>O<sub>4</sub>) and BiVO<sub>4</sub>, and their application in the photodegradation of aqueous solutions of sulfamethoxazole (SMX) under simulated solar radiation. We demonstrate that high-crystallinity single-phase monoclinic BiVO<sub>4</sub> was synthesized fast and efficiently using a solid-state method and, in combination with magnetic CoFe<sub>2</sub>O<sub>4</sub> particles, gives rise to a hybrid material that can be easily separated from the reaction medium, by applying an external magnetic field, without the need for further downstream treatments. |
