Cov khoom siv photocatalyst feem ntau yog N-hom semiconductor cov ntaub ntawv, uas muaj cov yam ntxwv ntawm qhov tsis tshua muaj band, 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. zoo dua photocatalytic zog, tab sis vim hais tias feem ntau ntawm lawv yog nquag mus rau chemical los yog photochemical corrosion, tus nqi ntawm precious hlau yog siab dhau heev lawm, thiab lawv tsis haum rau kev siv niaj hnub.
