I-SnO2 iyinto ebalulekile yenzwa ye-semiconductor enegebe elibanzi lebhendi, okuyi-Eg = 3.6 eV ekamelweni lokushisa.Ngenxa yokuthi ama-nanomaterials anezici zosayizi wezinhlayiyana ezincane kanye nendawo enkulu ethize, izici zokuzwa igesi zezinto zokwakha zingathuthukiswa kakhulu.Inzwa yegesi elungiselelwe ngayo inokuzwela okuphezulu futhi isetshenziswa kabanzi ekutholeni nasekubikezelweni kwamagesi ahlukahlukene avuthayo, amagesi okungcoliswa kwemvelo, igesi yemfucuza yezimboni namagesi ayingozi, njenge-CO, H2S, NOx, H2, CH4, njll.
Inzwa yomswakamo elungiswe nge-SnO2 njengoba isisekelo sezinto sinezinhlelo zokusebenza zokuthuthukisa indawo yasendlini, amagumbi emishini yezinsimbi ezinembayo, imitapo yolwazi, izindawo zemibukiso yobuciko, iminyuziyamu nokunye.Nge-doping-quantitative Co0, Co2O3, Cr2O3, Nb2O5, Ta2O5, njll. ku-SnO2, ama-varistors anamanani ahlukene okumelana angenziwa, asetshenziswa kakhulu kumasistimu kagesi, amasekhethi kagesi, nezinto zikagesi zasendlini.
