Cov khoom siv photocatalyst feem ntau yog N- cov khoom siv semiconductor, uas muaj cov yam ntxwv ntawm qhov sib txawv ntawm qhov qis, thiab cov khoom siv photocatalyst semiconductor feem ntau yog titanium dioxide.
ZrO2, ZnO, CdS, WO3, Fe2O3, PbS, SnO2, ZnS, SrTiO3, SiO2, thiab lwm yam. kuj yog cov khoom siv photocatalyst, txij li xyoo 2000, nws tau pom tias qee cov hlau muaj nuj nqis nano (platinum, rhodium, palladium, thiab lwm yam) muaj cov khoom siv zoo dua, tab sis cov tshuaj photocataly. corrosion, tus nqi ntawm cov hlau muaj txiaj ntsig yog siab dhau, thiab lawv tsis haum rau kev siv txhua hnub.
