Abstract

Visible photoactive AgBr/TiO₂ was immobilized on a SiO ₂@Fe₃O₄ magnetic support by solvothermal and sol-gel methods to form a AgBr-TiO₂/SiO₂@Fe ₃O₄ magnetic photocatalyst. Samples were characterized by X-ray diffraction, high-resolution transmission electron microscopy and magnetometry. Hetero-structured AgBr/TiO₂ was well seeded on the shell-core SiO₂@Fe₃O₄ structure. The AgBr-TiO₂/SiO₂@Fe₃O₄ magnetic photocatalyst exhibited high photocatalytic activity in the degradation of methylene blue under visible light. The photocatalyst was superparamagnetic, which is beneficial for facile magnetic separation.
