Cu2O nano ali ndi khola mankhwala katundu ndi amphamvu oxidizing mphamvu pansi pa zochita za kuwala kwa dzuwa, amene pamapeto pake akhoza kwathunthu oxidize organic zoipitsa m'madzi kubala CO2 ndi H2O.Chifukwa chake, nano Cu2O ndiyothandiza kwambiri pakuchiza kwamadzi otayira utoto osiyanasiyana.

Nano cuprous oxide nthawi zonse yakhala pachimake pa kafukufuku wa photocatalysis chifukwa cha mphamvu zawo zamphamvu za okosijeni, zochita zambiri zothandizira, komanso kukhazikika kwabwino.
