Facile fabrication of highly porous electrospun TiO2 nanotube and its photocataltytic application


Author(s): Hem Raj Pant

Abstract: In this work porous, hollow TiO2 fibers were fabricated using modified coaxial nozzle electrospinning set-up from a polymer sol-gel solution of CaCO3 and TiO2 precursor. Two solutions, a TiO2 precursor containing polyvinyl acetate (PVAc) solution with a small amount of CaCO3 and PVAc solution with a sufficient amount of CaCO3, were separately passed through the outer and inner nozzles, respectively. Hollow, porous TiO2 nanofibers were obtained by etching CaCO3 on calcined TiO2 fibers using dilute HCl. Field emission scanning electron microscopy images revealed that the as-fabricated TiO2 fibers were nanotubes with porous walls. Such a highly porous TiO2 nanotubes exhibited higher photocatalytic activities toward degradation of Rhodamine B in comparison to the other nanostructured TiO2 materials such as commercial P25 nanoparticles and regular TiO2 nanofibers.
