Cov duab thaij duab xws li Graphene yog cov ntaub ntawv muaj zog heev tab sis cov tswv yim muaj zog heev nrog rau kev tsim khoom, thiab cov hau kev siv sijhawm, thiab cov qauv kim thiab tsis yog ib puag ncig phooj ywg.
Nrog rau kev tsim cov nyiaj ntau ntawm graphene, txhawm rau kov yeej cov kev nyuaj, cov kws tshawb fawb ntawm Openity, suav nrog Options, suav nrog Optics, suav nrog Optics, suav nrog Optics, suav nrog Optics, suav nrog Optics, xws li cov khoom siv hluav taws xob, suav nrog optics, uas muaj ecology thiab biotechnology.
Cov kws tshawb nrhiav tau siv cais tawm mus rau extract graphene los ntawm ntuj ntxhia striolite. Lawv pom tias cov ntxhia hypophylite qhia cov kev cia siab zoo hauv kev tsim cov lag luam-teev graphene thiab graphene zoo li tshuaj.
Cov ntsiab lus carbon ntawm hypomphibole yuav txawv. Raws li cov txheej txheem carbon, hypomphibole tuaj yeem muaj cov peev xwm sib txawv. Qee hom yuav siv tau rau lawv cov khoom catalytic, thaum lwm hom muaj cov khoom muaj xyoob ntoo.
Cov qauv kev coj ua ntawm hypopyro ixia txiav txim siab lawv daim ntawv thov hauv cov txheej txheem oxidation-txo qis thiab ferrroalloy ntau lawm (siab silicon) cam khwb cia hlau.
Vim nws lub cev cov khoom siv lub cev, kev ceev ceev, lub zog zoo thiab hnav tsis kam lees, hypophylite kuj muaj ntau yam organic, yog li nws tuaj yeem siv ua cov khoom lim. Nws tseem pom tias muaj peev xwm tshem tawm cov khoom pub dawb tshaj plaws uas tuaj yeem paug cov dej paug.
Lub hypopyroupe qhia lub peev xwm los ntxuav tawm thiab ua kom huv cov dej los ntawm cov kab mob, cov kab mob, cov kab tsuag yooj yim, ntsuab algae. Vim nws lub siab catalytic thiab txo cov khoom, magnesia feem ntau siv los ua adsorbent rau kev kho kom dej khib nyiab.
(a) X13500 magnification thiab (b) x35000 magnification DEM duab ntawm dispersed hypophylite qauv. (c) Raman spectrum ntawm kev kho hypophlite thiab (d) XPS Spectrum ntawm cov kab carbon kab hauv hypophylrite spectrum
Graphene extraction
Los npaj cov pob zeb rau graphene extraction, ob siv lub vijtsam electron tsom (SEM) los tshuaj xyuas cov hlau hnyav thiab porosity hauv cov qauv. Lawv kuj siv tau lwm txoj hauv kev Kuaj cov qauv los xyuas cov qauv txheej txheem dav dav thiab muaj ntawm lwm cov zaub mov hauv lub hypomphibole.
Tom qab tshuaj ntsuam xyuas thiab npaj tiav lawm, cov kws tshawb nrhiav tau rho tawm graphene los ntawm kev siv cov qauv ntawm karelia siv cov digital ultrasonic huv.
Txij li cov qauv ntau tuaj yeem siv tau siv hom qauv no, tsis muaj kev pheej hmoo ntawm cov qauv hauv theem ob, thiab lwm txoj hauv kev tsis tas yuav tsum tau ua.
Txij li thaum cov teeb meem txawv tshaj plaw tau tshaj tawm hauv kev tshawb fawb dav dav hauv zej zog, ntau cov hau kev thiab cov tswv yim tau tsim. Txawm li cas los xij, ntau ntawm cov hau kev no yog cov txheej txheem ntau dua lossis xav tau siv tshuaj lom neeg thiab muaj kuab tshuaj oxidizing thiab txo tus sawv cev.
Txawm hais tias graphene thiab lwm cov duab thaij duab muaj peev xwm pom tau zoo R & D txoj kev vam meej, cov txheej txheem siv cov ntaub ntawv no tseem nyob hauv kev txhim kho. Ib feem ntawm kev sib tw yog ua kom pom cov graphene extraction raug nqi-zoo, uas txhais tau tias kev nrhiav txoj cai tsis yooj yim thev naus laus zis yog tus yuam sij.
Qhov kev sib cais no lossis cov khoom siv hluavtaws muaj zog thiab ib puag ncig tsis zoo, thiab lub zog ntawm cov kws tshaj lij duab, yog li txo qhov kev cia siab ntawm graphene.
Daim ntawv thov ntawm ultrasonic tshuaj ntxuav hauv graphene synthesis tshem tawm cov kev pheej hmoo thiab cov nqi cuam tshuam nrog ntau kauj ruam thiab tshuaj lom neeg. Kev thov cov qauv no mus rau lub ntuj ntxhia hypophylite txiav txoj kev rau txoj kev tshiab ib puag ncig kev tsim graphene.
