Lunar dust has been a grave concern since the Moon was considered as a probable habitat of human in that it may cause profound distress over human activity from health issue to mechanical failure. In the further Martian or lunar space project towards stable residence for human beings, removal of lunar or Martian dust is of paramount importance. The most advanced method of filtration is adopted to attack the problem. Filtration of dust by microfiber-based media has been successful in various areas; however, its performance as the filter cannot meet recent challenging needs in energy efficiency and highly abrasive charged particles. We introduce ceramic nanofiber-based filtration media fabricated via electrospinning via a novel aqueous sol to form TiO_2 composite nanofibers filters. Ceramics including TiO_2 are anticipated to be more stable than polymers in harsh environment in space. TiO_2 composite nanofibers filter mats from the aqueous sol method show good mechanical stability.
