Fabrication of unique ribbon-like porous LaFeO3 nanofibers photocatalyst via electrospinning

Novel LaFeO₃ ribbon-like porous nanofibers have been fabricated by electrospinning utilizing sol–gel precursors, followed by heat treatment at 600 °C for 2 h. The crystal structure, surface morphology, and microstructure were investigated by thermogravimetry–differential thermal analysis, X-ray diffraction, scanning electron microscopy, and transmission electron microscopy, respectively. The photocatalytic activity was investigated for the photodegradation of methylene blue aqueous solution. The result shows that the ribbon-like porous nanofibers exhibit excellent photocatalytic activity compared with ultrafine LaFeO₃ nanofibers and LaFeO₃ powders.
