Preparation of high-porous TiO2 nanofibers by electro spinning utilization of PVP-toluene solution |
| 초록 |
High-porous TiO2 nanofibers with crystalline structure of anatase and high-surface area were prepared by sol-gel process and electro spinning. TiO2 nanofibers were prepared by added pore agent for DSSC of high-solar conversion efficiency. In this study, high-porous TiO2 nanofibers were prepared for DSSC by electro spinning to sol-gel process used precursors of titanium tetraisopropoxide (TTIP) and toluene to pore-forming agent. TiO2 nanofibers prepared using toluene to pore-forming agent had high-porous in surface morphology. TiO2 nanofibers were prepared by calcinations process. The surface morphology of nanofibers was examined by scanning electron microscopy (SEM) and x-ray diffraction (XRD). The average diameter of these nanofibers was 80~150nm. Porosity of nanofibers was characterized using brunauer emmett teller (BET). Structure of the sintered composite was characterized using (TGA-DSC). |
