- Abstract
- In this study, we synthesized photoresponsible magnetic-cored dendrimers with photocatalytic terminals using nanomagnetite and nanoscale TiO2 powder for magnetic recovery, reuse, and photocatalytic activity. Magnetic core part was synthesized by coprecipitating ferrous and ferric iron ion solution using ammonia water, and applied the sematerials as magnetic core to build dendrimer structure upon. The prepared magnetic-cored dendrimers were modified with photocatalytic terminals. Magnetic-cored dendrimer with photocatalytic terminals (MDP) took terminal groups of TiO2 nanoparticles by terminal functional groups bonded surface of TiO2 chemically. The synthesized MDP has the optimal structure as a photocatalyst for advanced oxidation processes(AOPs) because of available surfaces of TiO2 and magnetite. MDP can photocatalytic Degradation of a Dye, such as Methyl orange and so on. Synthesized the presence of the functional groups of MDP were evidenced from the Fourier transform-infraredspectra (FT-IR), Field Emission Scanning Electron Microscope(FESEM, Supra 55VP, Carl Zeiss).
