Paper Title
Preparation of Titania Fibers at Various Calcination Temperatures and their Photocatalytic Activity

Abstract
Titanium dioxide fibers were prepared by electro spinning technique followed by calcined in the temperature range of 450C - 850C in air atmosphere. The surface morphology of the as-spun fibers showed that the micrography of the fibers are continuous and non-woven with an average diameters range from 100 to 200 nm. The amorphous as-spun fibers convert to anatase crystallized at 450C. The anatase crystallized fibers transform to rutile phase upon 850C. Brunauer-Emmett-Teller surface areas measured were shown dependently on calcination temperatures. Using the calcined titanium dioxide fibers as catalysts, photocatalytic degradation of methylene blue solution was carried out under Ultra-Violet light region. Approximately 2.3% of methlylene blue was degraded after 90 minutes in the absence of catalyst. Photdegradation of methylene blue using the calcined titanium dioxide fibers as a catalyst increased to 39%. According to the results, calcination temperatures influenced the photocatalytic efficiency of the mesoporous titanium dioxide fibers. Keywords - Titanium Dioxide Fibers, Electrospining, Photocatalyticefficiency, Calcination.
