Abstract

The $TiO_2$/PAN based composite nanofibers having photocatalytic activity were prepared by sol-gel process, electrospinning and post-treatments. Electrospinning solution was prepared by mixture of $Ti(OBu)_4$, PAN, acetic acid and DMF with different ratio. As-spun nanofibers were treated with different way to prepare the anatase $TiO_2$/PAN nanofibers and the N-doped $TiO_2$/PAN nanofibers. In this study, the morphology and diameter of the electrospun and heat treated composite nanofiber were analyzed, and crystal structure of nanofiber after heat treatment and N-doping was analyzed. Furthermore, photocatalytic decomposition of the nanofiber, crystallized in various condition, against the malachite green aqueous solution, was evaluated.
