Copper oxide hmoov yog ib hom xim av xim av dub hlau oxide hmoov, uas yog dav siv.Cupric oxide yog ib hom multifunctional zoo inorganic khoom, uas yog tsuas yog siv nyob rau hauv printing thiab dyeing, iav, ceramics, tshuaj thiab catalysis. Raws li catalyst, catalyst carrier thiab electrode ua kom cov khoom siv, thiab tseem tuaj yeem siv los ua foob pob hluav taws, uas yog cov khoom tseem ceeb ntawm catalyst, tooj liab oxide hmoov tau dav siv hauv oxidation, hydrogenation, tsis muaj, Co, txo thiab hydrocarbon combustion.
Nano CuO hmoov muaj kev ua haujlwm zoo dua catalytic, xaiv thiab lwm yam khoom dua li cov tooj liab oxide loj loj.Piv nrog cov tooj liab oxide zoo tib yam, nano CuO muaj cov khoom siv hluav taws xob zoo heev, kho qhov muag thiab catalytic.Cov khoom siv hluav taws xob ntawm nano CuO ua rau nws nkag siab zoo rau cov khoom siv hluav taws xob. Sab nraud ib puag ncig xws li kub, av noo thiab lub teeb, Yog li ntawd, lub sensor coated nrog nano CuO hais tuaj yeem txhim kho cov lus teb ceev, rhiab heev thiab xaiv ntawm lub sensor.Lub spectral zog ntawm nano CuO qhia tau hais tias lub infrared nqus ncov ntawm nano CuO yog widened. Pom tseeb, thiab qhov tshwm sim xiav hloov pauv yog pom tseeb.Copper oxide tau npaj los ntawm nanocrystallization, Nws pom tau tias nano-tooj liab oxide nrog me me me me thiab zoo dispersion muaj ntau dua catalytic kev ua tau zoo rau ammonium perchlorate.
Daim ntawv thov piv txwv ntawm nano-tooj liab oxide
1 raws li catalyst thiab desulfurizer
Cu belongs rau kev hloov pauv hlau, uas muaj cov qauv hluav taws xob tshwj xeeb thiab nce thiab poob hluav taws xob sib txawv ntawm lwm pawg hlau, thiab tuaj yeem pom cov txiaj ntsig zoo catalytic ntawm cov tshuaj sib txawv, yog li nws tau siv dav hauv catalyst fieldThaum qhov loj ntawm CuO hais me me. Raws li nano-scale, vim muaj qhov tshwj xeeb ntawm ntau qhov chaw dawb electrons thiab lub zog saum npoo ntawm cov khoom siv nano, yog li ntawd, nws tuaj yeem pom cov kev ua haujlwm catalytic ntau dua thiab muaj qhov tshwj xeeb catalytic tshwm sim ntau dua li CuO nrog cov pa scaleNano-CuO yog cov khoom lag luam zoo heev desulfurization, uas. tuaj yeem qhia tau zoo heev ntawm qhov kub thiab txias, thiab qhov raug tshem tawm ntawm H2S tuaj yeem ncav cuag qis dua 0.05 mg m-3Tom qab kev ua kom zoo, lub peev xwm nkag tau ntawm nano CuO nce mus txog 25.3% ntawm 3 000 h-1 airspeed, uas siab dua li ntawm lwm cov khoom desulfurization. ntawm tib hom

2 Daim ntawv thov ntawm nano CuO hauv sensors
Cov sensors tuaj yeem muab faib ua lub cev sensors thiab tshuaj sensors Lub cev lub cev yog ib qho khoom siv uas siv lub cev sab nraud xws li lub teeb, suab, hlau nplaum lossis qhov kub thiab txias raws li cov khoom thiab hloov cov khoom kuaj pom lub cev xws li lub teeb thiab qhov kub thiab txias rau hauv hluav taws xob signalsChemical sensors yog cov cuab yeej hloov pauv. cov hom thiab cov ntsiab lus ntawm cov tshuaj tshwj xeeb rau hauv cov teeb liab hluav taws xob.Chemical sensors yog tsim los ntawm kev siv cov kev hloov hluav taws xob xws li electrode muaj peev xwm ncaj qha los yog tsis ncaj thaum cov ntaub ntawv rhiab heev nyob rau hauv kev sib cuag nrog molecules thiab ions nyob rau hauv cov tshuaj ntsuam xyuasSensors yog dav siv nyob rau hauv ntau lub teb. , xws li kev saib xyuas ib puag ncig, kev kuaj mob, kev ntsuas huab cua, thiab lwm yam.Nano-CuO muaj ntau yam zoo, xws li thaj chaw tshwj xeeb ntawm qhov chaw, kev ua haujlwm siab, cov khoom siv lub cev tshwj xeeb thiab qhov loj me me, uas ua rau nws nkag siab zoo rau sab nraud ib puag ncig, xws li Qhov kub thiab txias, lub teeb thiab noo noo Siv nws mus rau thaj tsam ntawm cov sensors tuaj yeem txhim kho cov lus teb ceev, rhiab heev thiab xaiv qhov sensors.
3 Anti-sterilization kev ua tau zoo ntawm nano CuO
Cov txheej txheem tshuaj tua kab mob ntawm cov hlau oxides tuaj yeem piav qhia yooj yim raws li hauv qab no: nyob rau hauv lub zog ntawm lub teeb nrog lub zog loj dua li qhov sib txawv ntawm qhov sib txawv, cov khoom tsim hluav taws xob sib cuam tshuam nrog O2 thiab H2O hauv ib puag ncig, thiab cov khoom tsim tawm dawb radicals xws li cov pa oxygen reactive. Cov tsiaj muaj tshuaj lom nrog cov organic molecules hauv cov hlwb, yog li decomposing cov hlwb thiab ua tiav lub hom phiaj antibacterialAs CuO yog p-hom semiconductor, muaj qhov (CuO) +. nano-CuO muaj peev xwm tiv thaiv kab mob zoo tiv thaiv kab mob ntsws thiab Pseudomonas aeruginosa.
