Magnetically Recoverable Core–Shell Nanocomposites with Enhanced Photocatalytic Activity
Open accessAbstract
Core–shell structured Fe 3 O 4/SiO 2/TiO 2 nanocomposites with enhanced photocatalytic activity that are capable of fast magnetic separation have been successfully synthesized by combining two steps of a sol–gel process with calcination. The as‐obtained core–shell structure is composed of a central magnetite core with a strong response to external fields, an interlayer of SiO 2, and an outer layer of TiO 2 nanocrystals with a tunable average size. The convenient control over the size and crystallinity of the TiO 2 nanocatalysts makes it possible to achieve higher photocatalytic efficiency than that of commercial photocatalyst Degussa P25. The photocatalytic activity increases as the thickness of the TiO 2 nanocrystal shell decreases. The presence of SiO 2 interlayer helps to enhance the photocatalytic efficiency of the TiO 2 nanocrystal shell as well as the chemical and thermal stability of Fe 3 O 4 core. In addition, the TiO 2 nanocrystals strongly adhere to the magnetic supports through covalent bonds. We demonstrate that this photocatalyst can be easily recycled by applying an external magnetic field while maintaining their photocatalytic activity during at least eighteen cycles of use.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
