A composite magnetic photocatalytic titania( photoactive shell)/polyaniline( intermediate layer)/ferroferric oxide( magnetic core) fluid was prepared by microemulsion polymerization and hydrothermal methods without the requirement for a drying or grinding process. The prepared composite particles were characterized by X-ray diffraction( XRD),transmission electron microscopy( TEM),scanning electron microscopy( SEM),Fourier transform infrared( FT-IR) spectroscopy,and vibrating sample magnetometry( VSM). The p...
