Mafirimu eCarbon akadai segraphene zvinhu zvakapfava asi zvakasimba zvine simba rekushandisa, asi zvinogona kunetsa kugadzira, kazhinji zvinoda vashandi vakawanda uye nzira dzinotora nguva, uye nzira dzacho dzinodhura uye hadzina hushamwari.
Nekugadzirwa kwe graphene yakawanda, kuitira kukunda matambudziko anowanikwa mukushandisa nzira dzemazuva ano dzekuchera, vatsvakurudzi veBen Gurion University yeNegev muIsrael vakagadzira "green" graphene extraction method inogona kushandiswa kune A yakawanda yakasiyana-siyana. yeminda, kusanganisira optics, zvemagetsi, ecology uye biotechnology.
Vatsvagiri vakashandisa mechanic dispersion kubvisa graphene kubva kune yakasikwa mineral striolite.Vakaona kuti iyo mineral hypophyllite inoratidza tarisiro yakanaka mukugadzira maindasitiri-scale graphene uye graphene-senge zvinhu.
Iyo kabhoni yemukati ye hypomphibole inogona kunge yakasiyana.Zvinoenderana nekabhoni yemukati, hypomphibole inogona kuve neakasiyana mashandisirwo ekushandisa.Mamwe marudzi anogona kushandiswa kune yavo catalytic properties, nepo mamwe marudzi ane bactericidal properties.
Mamiriro ezvinhu ehypopyroxene anotarisisa mashandisiro azvo mukuita-oxidation-yekudzikisira maitiro, uye inogona zvakare kushandiswa pakuputika kwevira rekugadzira uye ferroalloy kugadzirwa kwe cast (yakakwira silicon) simbi yakakandwa.
Nekuda kwehunhu hwayo hwepanyama uye hwemagetsi, kuwanda kwehuwandu, simba rakanaka uye kushomeka kwekusagadzikana, hypophyllite inewo kugona kushambadza zvakasiyana siyana organic zvinhu, saka inogona kunyatso shandiswa sesefa zvinhu.Yakaratidzawo kugona kubvisa mahara radical particles anogona kusvibisa matsime emvura.
Iyo hypopyroxene inoratidza kugona kuuraya utachiona uye kuchenesa mvura kubva kubhakitiriya, spores, tupukanana tudiki uye bhuruu-girinhi algae.Nekuda kwekukwirira kwayo kunobatsira uye kudzikisira zvivakwa, magnesia inowanzoshandiswa seye adsorbent yekuchenesa mvura.
(a) X13500 magnification uye (b) X35000 magnification TEM mufananidzo weiyo yakapararira hypophyllite sampuli.(c) Raman spectrum yeyakaitwa hypophyllite uye (d) XPS spectrum ye carbon line mu hypophyllite spectrum.
Graphene extraction
Kugadzirira matombo ekubvisa graphene, vaviri ava vakashandisa scanning electron maikorosikopu (SEM) kuongorora kusvibiswa kwesimbi inorema uye porosity mumasampuli.Vakashandisawo dzimwe nzira dzemurabhoritari kuti vatarise kuumbwa kwemaitiro uye kuvapo kwemamwe mamineral mu hypomphibole.
Mushure mekuongorora kwemuenzaniso uye kugadzirira kwapera, vatsvakurudzi vakakwanisa kubvisa graphene kubva kune diorite mushure mekugadzirisa sampuli kubva kuKarelia vachishandisa digital ultrasonic cleaner.
Sezvo nhamba huru yemasampuli inogona kugadziriswa uchishandisa nzira iyi, hapana njodzi yekusvibiswa kwechipiri, uye inotevera nzira dzekugadzirisa nzira hadzidiwi.
Sezvo izvo zvinoshamisa zvimiro zvegraphene zvave zvichizivikanwa zvakanyanya munharaunda yakafara yesainzi yekutsvagisa, nzira dzakawanda dzekugadzira uye synthesis dzakagadzirwa.Nekudaro, dzakawanda dzeidzi nzira dzingava dzakawanda-nhanho maitiro kana dzinoda kushandiswa kwemakemikari uye yakasimba oxidizing uye kuderedza vamiririri.
Kunyangwe graphene nemamwe mafirimu ekabhoni aratidza kugona kukuru kwekushandisa uye akawana budiriro yeR&D, maitiro ekushandisa zvinhu izvi achiri pasi pekuvandudzwa.Chikamu chedambudziko ndechekuita kuti graphene iwedzere mari-inoshanda, zvinoreva kuti kutsvaga tekinoroji yekuparadzira ndiyo kiyi.
Iyi nzira yekuparadzira kana yekubatanidza inonetsa uye haina hushamwari, uye kusimba kwetekinoroji iyi kunogona kukonzera kukanganisa mugraphene inogadzirwa, nekudaro ichideredza hunotarisirwa kunaka kwegraphene.
Iko kushandiswa kwema ultrasonic cleaners mugraphene synthesis kunobvisa njodzi uye mutengo unobatanidzwa neakawanda-nhanho uye makemikari nzira.Kushandisa nzira iyi kune yakasikwa mineral hypophyllite yakagadzira nzira yenzira itsva yezvakatipoteredza yekugadzira graphene.
