Hollow rice grain-shaped titanium dioxide (TiO2) nanostructures (NSs) with the radius of 200–300 nm are fabricated by electrospinning titanium isopropoxide solution and further calcination. The resulting hollow rice grain-shaped TiO2 NSs are highly porous, which are beneficial to the infiltration of...
