Fabrication of hierarchically porous inorganic nanofibers by a general microemulsion electrospinning approach.

Ultraporous inorganic oxide nanofibers are fabricated by a general microemulsion electrospinning approach. The stable microemulsion spinning solution comprises metal alkoxide as the consecutive phase and paraffin oil as the dispersion phase as well as pore-forming template. After calcination, inorganic nanofibers with well-controllable high porosity are obtained with a typical composite structure of mesopores and macropores. © 2011 WILEY-VCH Verlag GmbH & Co.
