| heal.abstract | This study reports on the fabrication of magnetically, responsive hollow Mania capsules by confining the superparamagnetic Fe3O4 nanoparticles within a hollow and porous titania (TiO2) shell. The employed protocol involves precipitation of Mania shell on the magnetite (Fe3O4) encapsulated polystyrene beads followed by the calcination of resulting composite particles at elevated temperature. Scanning electron microscopy and transmission electron microscopy reveal the presence or a thick, complete but irregular Mania shell on the magnetic polystyrene beads alter the ternplating process. Electron energy loss mapping image analysis has been employed to in the spatial distribution of titania and magnetite phases of magnetic hollow Mania capsules (MHTCs). Magnetic characterization indicates that both titania-coated magnetic polystyrene beads (TMPBs) and MHTCs arc superparamagnetic in nature with the saturated magnetizations of 5.6 and 8.1 emu/g. respectively. X-ray diffraction (XRD) analysis reveals that Mania shell of these capsules is composed of photoactive anatase phase. Nitrogen adsorption-desorption analysis has been employed to estimate the specific surface area and the average pore diameter of the fabricated hollow structures. Photocatalytic activity of the fabricated MHTCs for the photodegradation of rhodamine 6G dye has been demonstrated and compared with that of bulk Mania nanoparticles. | en |
