 Hybrid porous particles (HPPs) of poly(methyl methacrylate-divinylbenzene) containing Fe₃O₄ and BiVO₄ nanoparticles were prepared via the microsuspension/iodine transfer polymerization and used for dye removal. The presence of poly(methacrylic acid-block-poly(methyl methacrylate-3-(trimethoxysilyl) propyl methacrylate) as porogen and surface modifier affected the morphology, metal oxide loading, porosity and colloidal stability of the synthesized particles. These HPPs could effectively adsorb methylene blue (MB) up to 235 mg/g-BiVO₄. They could be degraded by the photocatalytic process and reused several times (up to 5 cycles) with high MB removal performance (> 85%) by applying the external magnetic field.
