Mayelana nezinto zokwakha ze-Mngene: Izinyathelo ezintathu zikuthatha ukuze uqonde MXENE | ISigaba Sokubhala | I-Metal | Mxene | uhlobo

July 11, 2023

Eminyakeni yamuva nje, i-Mxene, isakhiwo esinjengemidwebo esitholwe ukwelashwa kwesigaba sakwaMax, sidonsele ukunakekelwa okuningana kocwaningo, futhi abalingani abaningi banelukuluku ngalokhu okuqukethwe. Namuhla, i-Xiaobian izokuthatha ukuze uqonde izinto ezithandwayo ze-2D.

Yini i-Mxene?
I-MNENE yisakhiwo esifana nethoshi esitholwe ukwelashwa kwesigaba max. Ifomula ethile yama-molecular yesigaba max i-MN + 1axn (n = 1, 2 noma 3), lapho uMin abhekisela ezintweni eziwusizo zeqembu leqembu, futhi u-X abhekisela ku-C kanye / noma izakhi.
Ngoba i-MX ine-bond energy eqinile futhi inomsebenzi wamakhemikhali asebenzayo, ingasuswa esigabeni se-max nge-etching ukuthola isakhiwo se-2D se-graphu - Mxene.
Umdwebo 1. Ukwakheka kwe-Crystal kwesigaba seMax kanye ne-Etched Mxene
Kusukela umbiko wokuqala we-Mxene (ti3c2tx, lapho i-T imele khona i-terminal yobuso, kufaka phakathi oh, o noma f) ngonyaka ka-2011, izinto eziningi ze-MXENE zenzelwe izinto zokucwaninga. Khazaei et al. Ihlongoze ukuthi isimo somhlabathi wezinto eziningi ze-Mxene (CR2CT2 noma i-CR2NO2) iyi-Ferromagnetic, nokuthi amapharamitha we-Seebeck we-semiconductor Mxene aphezulu kakhulu emazingeni aphansi. Zhang et al. Okokuqala okuhlongozwa ukuthi ama-monollayers we-MNEne (Ti22) abe nama-oda amabili wokuhamba umgodi ophakeme we-maggiture kanye nokuhamba okuphansi kwe-elektroni, futhi kamuva ukuqinisekisile ukuhamba okuphezulu okuphezulu ezihlolweni. Ngenxa yezakhiwo zayo ezihlukile, i-Mxene isetshenziswe kabanzi kuma-catalysts, ukuhlolwa kwe-Ion, ukuguqulwa kwe-Photothermal, ama-transistors e-Field Effect, oporologi bezinhlaka ze-hydrogen kanye nokuvuselelwa kwe-hydrogen involultion.

Ilungiselelwe kanjani i-Mnene?
Njengoba kuchaziwe ngenhla, i-ti3c2tx ilungiselelwe kusukela naguib et al okokuqala nge-etching ekhethwa nge-hydrofluoric acid (hf) emazingeni okushisa asekamelweni (i-RT). Abaphenyi abaningi ngokwengeziwe basebenzela ukuthola izindlela ezintsha zokwenza ama-Mxene amaningi. Naguib et al. Okokuqala kuhlongozwa ukuthi ngemuva kokususa ungqimba (al) ungqimba, i-MX (TI3C2) ungqimba isigaba se-MAX (Ti3c2), bese kuthi isigaba se-Ultrasonic, isigaba esisha se-TI3C2 singatholakala. Ngemuva kwalokho imiphumela yesikhathi soku-etching, izinga lokushisa, usayizi wezinhlayiyana kanye nomthombo we-ti3alc2 lapho kulungiswa i-2D TI3C2 ngendlela ye-HF yafundwa ngokuhlelekile. Ngaphezu kwalokho, amandla ebhondi futhi anquma izimo ezi-etching. Ukukhetha izimo ezifanele ze-etching kuyisihluthulelo sokuthola isivuno esikhulu nobumsulwa.
Kamuva, ekuhlolweni nge-ejenti ye-ejenti efanayo, ngaphezulu futhi ngaphezulu kutholwe ngempumelelo, kufaka phakathi i-TI2ctx, i-TA4CTX, i-NB2CTX, (NB0.8TX, (NB0.8ZTX. 2) I-4C3TX, ZR3C2TX kanye ne-HF3C2TX, lapho i-Mo2C iyi-Mxene yokuqala elungiselelwe yisigaba se-Mo2GA2C esikhundleni sesigaba seMax. Ngaphezu kwalokho, i-ZR3C2 iyi-Mxene elungiselelwe kusuka ku-ZR3AL3C5, okuyi-carbide yensimbi evamile ye-terrrary kanye ne-quathernary ehlanganisiwe enefomula ejwayelekile ye-mnal3cn + 2 ne-SI)] 4cn + 3, lapho uMna ama-MN) n ilingana no-1-3. I-Mxene entsha, i-HF3C2YX, yatholakala nge-Elective Etching HF3 [Al (SI)] 4c6. Lo mphumela uvula umnyango wokulungiswa kwenoveli ye-Mxene kusuka kwangaphambili okwedlule. Ngaphezu kwe-terpolymer Mxene ejwayelekile, i-anasori et al. Kubaliwe futhi kubikezelwe i-Odway M2D Carbides M2D Carbides m'm 'xene nge-density functional theory (DFT), futhi ilungiselele iMo2Tic2TX, iMo2Ti2CTX kanye ne-CR2TICXX kanye ne-CR2TICXXX kanye ne-EtChing Agent.
