Fabrication and characterization of CoTiO3 nanofibers by sol–gel assisted electrospinning

Abstract Continuous CoTiO 3 nanofibers have been successfully synthesized by a sol–gel assisted electrospinning method followed by calcination at 600 °C in air. The scanning electron microscopy (SEM) results reveal that the obtained CoTiO 3 nanofibers are 220 nm in diameter and several micrometers in length. The X-ray diffraction (XRD) analysis shows that the nanofibers possess highly crystalline structure without any impurity phase. In contrast, the CoTiO 3 nanoparticles synthesized at the identical conditions by a sol–gel route have impurities including Co 3 O 4 and TiO 2 . Moreover, the electrospun CoTiO 3 nanofibers are endowed with a higher specific surface area compared with the nanoparticle counterparts, which results from the regular one dimensional (1D) morphology without any detectable agglomeration and a rough surface.
