In this work we present detailed optimization of the titania-based electrospun
nanofibers fabrication procedure. The starting solutions were prepared from
stabilized titanium (IV) isopropoxide and different polymers, such as PCL
(polycaprolactone) and PVP (polyvinylpyrrolidone). We report on the correlation
between the processing parameters and functional properties of as synthesized
fibers. Microstructural analyses performed on SEM and FE-SEM have revealed
branchy morphology of nanofibers uniform in shape and size. Anatase phase in as
prepared and calcined samples was disclosed by in-depth analysis of TEM images
and SAED spectra. The obtained fibers were used in UV/Vis photocatalytic reactor
for degradation of dye-contaminated water solutions. Promising results were
observed showing improved behavior compared to referent samples. Furthermore,
the influence of various dopants on the photocatalytic properties was investigated.
