Nano WO3 ili ndi kukhazikika kwa photocatalytic, komanso imakhala ndi mphamvu yothandiza pakuwonongeka kwa zowononga m'madzi.

1. Kugwiritsa ntchito m'munda wa kuyeretsa mpweya.The luso photocatalytic m'munda wa kuyeretsa mpweya zikutanthauza kuti photocatalysis akhoza mwachindunji ntchito mpweya mu mlengalenga monga okosijeni, bwino kuwola m'nyumba ndi kunja organic zoipitsa, ndi oxidize ndi kuchotsa oxides nayitrogeni, sulfide, ndi zosiyanasiyana fungo mu mlengalenga.Zomwe zimachitika ndizochepa, zomwe ndi njira yabwino kwambiri yoyeretsera mpweya.

2. Kugwiritsa ntchito madzi otayira.Zoyeserera zomwe zidanenedwapo m'mbuyomu pogwiritsa ntchito nano tungsten oxide ngati photocatalyst kuchitira kusindikiza ndi kudaya madzi oyipa.Zotsatira zake zidawonetsa kuti kuwala kowoneka kumatulutsa ufa wa semiconductor woyimitsidwa munjira yamadzi, utotowo umawonongeka kukhala CO2, H2O, N2, ndi zina zambiri, potero amachepetsa COD ndi chroma.
