Novel Core-Shell Metal Oxide Nanofibers with Advanced Optical and Magnetic Properties

Summary

Coaxial electrospinning offers a direct route to core-shell metal oxide fibres, and this study exploits it to combine two functions that are normally at odds: a magnetic core and a photocatalytic shell. Fe₃O₄-Fe₂NiO₄/NiO core-shell nanofibres were fabricated and their optical and magnetic properties characterised, with the fabrication parameters optimised to control the architecture. The appeal for water treatment is practical: the shell degrades pollutants photocatalytically, while the magnetic core allows the catalyst to be recovered from the treated water with a magnet rather than by filtration.
