We have shown that photoresponsible magnetic-cored dendrimer with photocatalytic functional groups can use nanoscale magnetite and TiO₂for magnetic recovery, photocatalytic activity. Nanomagnetite of magnetic core part was prepared by coprecipitating ferric and ferrouous iron ion solution using ammonium hydroxide. The synthesized magnetic-cored dendrimers were modified with photocatalytic functionals for environmental application. Magnetic-cored dendrimer with photocatalytic terminal (MDP) took functional group of TiO₂nanoparticles by functional group bonded surface of TiO₂chemically. The morphology of MDP depended on the TiO₂nanoparticles. The prepared MDP has the optimal structure as a catalyst for advanced oxidation processes (AOPs) because of available surface of TiO₂and magnetite. In terms of catalytic activity the synthesized MDP were almost comparable to the commercial P25 TiO₂photocatalyst. In addition, the easily recoverable magnetic photocatalysts showed good reusability.
