In this work, titanium dioxide (TiO2) nanofibers doped with 0.5–5 mol%
zirconium ions (Zr4+) were synthesized by combining the sol-gel process and
electrospinning method, and calcined at 500 °C. The morphological, structural and
optical properties of pure and Zr-doped TiO2 nanofibers were investigated. According to
the XRD and FTIR analyses, the addition of Zr as a dopant suppressed the
transformation of anatase to rutile phase. Scanning electron microscopy showed that all
fibers were smooth, fragile and randomly oriented after the calcination process. HRTEM
analysis revealed that Zr4+ ions were incorporated at the substitutional sites in the anatase
TiO2 crystalline lattice. The photocatalytic efficiency for degradation of methylene blue
(MB) was examined for both pure and Zr-doped TiO2 samples. Nanofibers doped with
1% of Zr4+ ions have shown the highest photocatalytic activity of 98%, wich can be
explained by considering lower PL intensity in the PL spectrum of... this sample,
indicating suppressed electron-hole recombination.
