Cov yam ntxwv thiab kev siv ntawm nano tooj liab oxide Cuo

Copper oxide hmoov yog ib hom 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 luam ntawv thiab dyeing, iav, ceramics, tshuaj thiab catalyst. hmoov tau siv dav hauv oxidation, hydrogenation, tsis muaj, Co, txo thiab hydrocarbon combustion.

Nano CuO hmoov muaj kev ua haujlwm zoo dua catalytic, kev 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 tshaj plaws, kho qhov muag thiab catalytic. Cov khoom siv hluav taws xob ntawm nano CuO ua rau nws nkag siab zoo rau qhov chaw sab nraud xws li kub, av noo thiab lub teeb, yog li ntawd, lub sensor coated nrog nano cov lus teb tau zoo heev, Cuens particle zoo dua. Lub sensor.The spectral zog ntawm nano CuO qhia tau hais tias lub infrared nqus ncov ntawm nano CuO yog widened obviously, thiab lub xiav hloov phenomenon yog pom tseeb.Copper oxide tau npaj los ntawm nanocrystallization, Nws pom tau hais tias nano-tooj ​​liab oxide nrog me me particle loj thiab zoo dispersion muaj ntau dua catalytic kev ua tau zoo rau ammonium peroxide.

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 ntawm cov tshuaj lom neeg sib txawv, yog li nws tau siv dav hauv catalyst fieldThaum qhov loj ntawm CuO particles me me li nano-scale, vim muaj qhov tshwj xeeb ntau qhov chaw dawb electrons thiab siab zog ntawm nano-materials, nws muaj peev xwm ua kom muaj zog ntau dua ntawm cov khoom siv peculiar. catalytic phenomenon tshaj CuO nrog cov pa scaleNano-CuO yog ib qho zoo heev desulfurization khoom, uas muaj peev xwm qhia tau zoo heev ua hauj lwm nyob rau hauv ib txwm kub, thiab qhov raug tshem tawm ntawm H2S tuaj yeem ncav cuag qis dua 0.05 mg m-3Tom qab optimization, lub peev xwm nkag tau ntawm nano CuO nce mus txog 25.3% ntawm qhov siab tshaj li ntawm 30 desurization ntawm 30% ntawm huab cua ceev ntawm 10f. cov khoom ntawm tib hom

2 Daim ntawv thov ntawm nano CuO hauv sensors

Sensors tuaj yeem muab faib ua lub cev sensors thiab tshuaj sensors Physical sensor 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 uas hloov cov hom thiab cov ntsiab lus ntawm cov tshuaj tshwj xeeb rau hauv hluav taws xob cov teeb liab. Thaum rhiab cov ntaub ntawv nyob rau hauv kev sib cuag nrog molecules thiab ions nyob rau hauv lub ntsuas tshuajSensors yog dav siv nyob rau hauv ntau yam teb, xws li ib puag ncig saib xyuas, kev kho mob kev kuaj mob, huab cua, thiab lwm yam.Nano-CuO muaj ntau yam zoo, xws li qhov chaw tshwj xeeb nto, siab nto ua hauj lwm, tshwj xeeb lub cev muaj zog thiab tsis tshua muaj me me, uas ua rau nws rhiab heev rau sab nraud ib puag ncig, xws li qhov kub thiab txias, lub teeb pom kev zoo tuaj yeem txhim kho qhov ntsuas kub, lub teeb thiab lub teeb. rhiab heev thiab selectivity ntawm 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 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 dawb radicals tsim xws li cov pa oxygen reacts chemically nrog cov organic molecules hauv cov hlwb, yog li decomposing lub hom phiaj ntawm cov kab mob Cu-A. semiconductor, muaj qhov (CuO) + .Nws tuaj yeem cuam tshuam nrog ib puag ncig thiab ua lub luag haujlwm tiv thaiv kab mob los yog bacteriostatic Kev tshawb fawb tau pom tias nano-CuO muaj peev xwm tiv thaiv kab mob zoo tiv thaiv kab mob ntsws thiab Pseudomonas aeruginosa.
