Electrospinning of polymer nanofibers has been studied extensively and has shown to be possible via
stable, reproducible and controllable processes. The development of more inert nanofibers with higher
thermal and chemical resistance extends the application field towards challenging purification and
separation obstacles of today. By direct electrospinning of a tetraorthosilicate (TEOS) based sol–gel
solution, without a sacrificing carrier polymer, dense ceramic silica nanofibers can be produced. A
humidity or temperature induced wettability-switch from highly hydrophobic after electrospinning to
superhydrophilic makes the resulting silica nanofibrous membranes ideal for fast gravity-driven
separation, especially upon tuning the surface chemistry and the functionalization. This is showcased
for the separation of immiscible liquids and the photocatalytic degradation of organic micro-pollutants.
