Summary
Pharmaceutical residues in water are difficult to remove, and photocatalysts that work well are often hard to recover afterwards. This study addresses both problems with a single fibre architecture: Fe3O4-Fe2NiO4/NiO core-shell nanofibres made by coaxial electrospinning, where the shell drives photocatalytic degradation of active pharmaceutical compounds while the magnetic core lets the spent catalyst be pulled out of the treated water with a magnetic field. The structural, optical, magnetic and photocatalytic properties are characterised together, since in this design they are inseparable.

Linari Electrospinning Systems
Coaxial electrospinning needle
Core and shell solutions were delivered through plastic tubing to a
coaxial needle (Linari Engineering, Pisa, Italy) with an inner diameter of 0.5 mm, the arrangement that produces the magnetic-core / photocatalytic-shell structure described here.
