Pore volume and distribution regulation of highly nanoporous titanium dioxide nanofibers and their photovoltaic properties

By combining the initial solvent volatilization and ultimate calcination to form highly nanoporous polystyrene/titanium dioxide (PS/TiO2) composite nanofibrous mats were fabricated via electrospinning, then the PS was removed afterwards by calcination, and finally porous TiO2 nanofibers were formed successfully. The porous structure of the nanofibers was characterized by field emission scanning electron microscopy and Brunauer-Emmett-Teller...
