SnO2 yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob semiconductor nrog qhov sib txawv ntawm qhov dav, uas yog Eg = 3.6 eV ntawm chav tsev kub.Vim hais tias nanomaterials muaj cov yam ntxwv ntawm me me particle loj thiab loj tshwj xeeb nto, lub gas-sensing zog ntawm cov ntaub ntawv yuav ua tau zoo heev.Cov pa roj sensor npaj nrog nws muaj siab rhiab heev thiab yog dav siv nyob rau hauv lub nrhiav kom tau thiab forecasting ntawm ntau yam combustible gases, ib puag ncig muaj kuab paug gases, industrial khib nyiab roj thiab teeb meem gases, xws li CO, H2S, NOx, H2, CH4, thiab lwm yam.
Cov av noo sensor npaj nrog SnO2 raws li cov khoom siv hauv paus muaj kev siv hauv kev txhim kho qhov chaw sab hauv tsev, cov cuab yeej ntsuas ntsuas qhov tseeb, cov tsev qiv ntawv, kos duab, tsev cia puav pheej thiab lwm yam.Los ntawm doping-quantitative Co0, Co2O3, Cr2O3, Nb2O5, Ta2O5, thiab lwm yam nyob rau hauv SnO2, varistors nrog txawv qhov tseem ceeb kuj yuav ua tau, uas yog dav siv nyob rau hauv lub hwj chim systems, hluav taws xob circuits, thiab cov khoom siv hauv tsev.
