Selective fabrication of porous iron oxides hollow spheres and nanofibers by electrospinning for photocatalytic water purification

Porous hematite (α-Fe2O3) hollow spheres and nanofibers could be selectively obtained via electrospinning and subsequent thermal decomposition in air. Compared with the α-Fe2O3 nanofibers, the porous spheres exhibited superior photocatalytic performance.111
