We report a facile “hydrothermal etching assisted crystallization” route to synthesize Fe3O4@titanate yolk-shell microspheres with ultrathin nanosheetsassembled double-shell structure. The as-prepared microspheres possess a uniform size, tailored shell structure, good structural stability, versatile ion-exchange capability, high surface area, large magnetization, and exhibit a remarkable catalytic performance. This study reports on the fabrication of magnetically responsive hollow titania capsules by confining the superparamagnetic Fe3O4 nanoparticles within a hollow and porous titania (TiO2) shell. The employed protocol involves precipitation of titania shell on the magnetite (Fe3O4) encapsulated polystyrene beads followed by the calcination of resulting composite particles at elevated temperature. |
