- Abstract
- Magnetic-cored dendrimer can effectively function as an absorbent and be recovered by magnetic force. Monodisperse nano TiO₂ can be synthesized through a solvothermal method in an oleic acid system. Divergence through coprecipitation and rotation growth was used for synthesis TiO₂ functionalized magnetic-cored dendrimer. Nano TiO₂-particles clump together, and thereby reduce the advantages associated with the surface area of single nano TiO₂-particle. Dendrimer’s Fractal structure makes nano-TiO₂ particles of functional group disperse in the water, so we can make full use of the surface area of each nano-particle and improve photocatalysis. This new material was characterized by Scanning electron microscopy(SEM), Transmission electron microscopy(TEM), X-ray diffraction(XRD), Fourier transform-infrared spectroscopy(FT-IR), Energy dispersive spectroscopy(EDS) analysis.
