Ukubaluleka kwekhabhoni, enye yezinto ezibaluleke kakhulu empilweni, kuyabonakala. Kusukela inkathi ye-paleolithic, abantu baye bazama ukusebenzisa ikhabhoni ukuze bahlangabezane nezidingo zethu eziyisisekelo. Namuhla, ososayensi bathuthukise ngempumelelo izinto zekhabhoni ezigcwele, kusukela kumachashazi we-2D Carbon Quantuum, 1D Carbon Nanotubes noma ama-Graphine, i-graphene 2D kanye ne-3D Carbon Foam, nokunye, kusetshenziswe kabanzi emikhakheni eminingi. Ngakho-ke, izinto zekhabhoni nazo zidlala indima ebaluleke kakhulu emhlabeni esiphila kuzo, sikhonza izimpilo zethu. Inzuzo yezindleko ezingenakuqhathaniswa yenza kube iphayona nomholi emikhakheni eminingi yohlelo, futhi ingahlanganiswa nezinye izinto zokusebenza kangcono kwezinye izindawo ezithile.

Kusukela ukutholwa kwe-2D graphene, izinto eziningi ze-2D zifundwe kakhulu, njengezindwangu zensimbi yensimbi, ikakhulukazi i-sulcogenides kanye ne-nitrides, ne-hexagonal boron nitride, i-ldh, i-phosphene, phosphene, phosphene, phosphene, phosphene, phosphene, I-Germane, njll. Yize lezi zinto zokwakha ezi-2D zinesakhiwo esijwayelekile se-2D esizonke, izakhiwo ezithile zomzimba nezomzimba ziyahlukahluka ngokuya ngokwakheka kwamakhemikhali, okubuye kunikeze umkhaya wezicelo eziningi. Phakathi kwazo, i-carbide yensimbi yensimbi ebekiwe yinkanyezi eshisa kakhulu eminyakeni eyishumi edlule, okuthiwa yi-Mxene, ngenxa yezindawo zayo ezinjengegolide ezinamandla kagesi, amaqembu acebile aphezulu, anjenge-o, I-hydrophilicity enhle kakhulu kanye ne-elektronegativity engaphezulu nezinye izici ezibanzi ezinhle kakhulu. Njengoba yaqala yahlanganiswa ngo-2011, sekuyisihloko sokucwaninga esishisayo sabacwaningi emhlabeni wonke, ngoba siyazi ukuthi izinto eziningi ze-2D zikhombisa ukufakwa, ukubonwa kwe-miconductor noma ukutholakala kwe-Mxene uhlelo. Hhayi lokho kuphela, uma kuqhathaniswa nezinye izinto ezinezinhlangothi ezimbili, i-MNene inokwehlukahlukana kakhulu ngokususelwa ezingxenyeni ezithile ze-athomu, ngenxa yoku-oda kwe-atomic noma ezinhlanteni ze-atomic, kusuka ku-M2x2, kuya ku-M4x3 futhi Muva nje i-M5X4, eletha izingxenye ezingaphezu kwe-100 ezingaba khona ezinhlelweni ze-MNEne ezibonakalayo. Lokhu akunakuqhathaniswa nanoma iyiphi enye into kuze kube manje. Okubaluleke kakhulu, ngokuya ngemibandela ehlukene ye-etching kanye nezindlela zesigaba se-Presurson Max, inani elikhulu lamaqembu asebenzayo ebusweni be-Mxene angalawulwa, ukuze akwazi ukuqondiswa ngokwesimo sohlelo lokusebenza ukuklama ukwakheka okuhle kakhulu . I-Van der Waals Force phakathi kwezendlalelo ze-Mxene inganqotshwa ngosizo olulula lwensimu ye-ultrasonic, okuhambisana nokuphindisela kwe-elektroniki okwenziwe nge-electronegativity phakathi kwezendlalelo ze-Mxene, kanye ne-membrane ehlukile ye-membrane ene-Ultra -Flexibility kanye ne-Ultra-high activity ingatholwa ngokukhishwa okulula nokuhlunga. Ngenxa yalesi simo esihle kakhulu, i-2D Mnganene iyinhlangano evimba amabhlokhi wokwakha ahlukahlukene ahlukahlukene kusukela kutholakala okuvela ku-Catalysis, ukuzwela, amaseli elanga kanye nokuvikelwa kwe-electromagnetic, ukwelashwa kwamanzi kanye ne-biomedicine.

Kunezinhlangothi ezimbili kukho konke, yize izinto ze-Mngene zinezinzuzo eziningi ezinjengenhla, kepha ezimbi zayo ezinhlelweni ezithile zesicelo okufanele sibhekane nazo. Okwezinhlelo zokusebenza zokugcina amandla, ukuqina kukagesi okuphezulu kuka-Mnganene namandla amakhemikhali kungagcina inani elikhulu lokukhokhisa ngokuziphatha kwe-pseudocapacitance. Kodwa-ke, ukusebenza kwangempela kwe-electrochemical kwezinto zokwenziwa nge-elektrode ezisuselwa ku-M -ene-based electlene kuncike ngokuphelele kwizakhiwo ezingaphezulu ezilawulwa yizimo zokwenziwa, futhi zivame ukubhekana nezimo ezimbi zokuzibeka ngesikhathi ngesikhathi sokushaja isikhathi eside nemijikelezo. Igcizelela kakhulu ukuziphatha kwe-ion. Futhi isikhathi saso esiphakeme esiphakeme se-molecular sivame ukuba namazinga we-theoreticals we-theoretical angagculisi. I-Mxene esigabeni sayo esihlanzekile futhi kunzima ukuchaza njengokusebenza ngokwanele kwezicelo ze-catalytic. Kwezinye izinhlelo zokusebenza, isimo esifanayo sibe yiphazili enkulu yabacwaningi. Lapha, okunhlanganisela, kuyindlela ephumelela kunazo zonke, ngoba ingahlanganisa izinzuzo zezakhi ezahlukahlukene, inhlanganisela yalezi ezimbili ine- "Chemical Reaction" enokwenzeka Siza ukusebenza kwezinto ezisuselwa ku-M -ene ezingeni elisha.

Lapha, sifingqa ngokuhlelekile ukuhlanganiswa kwesakhiwo kwe- "1 + 1> 2", okungukuthi, "i-XD Carbon + 2D Mnganene = ∞". Ngokusho kobukhulu obuhlukahlukene be-matrix yekhabhoni, kusuka kubukhulu obuphansi kubukhulu obuphezulu, amachashazi we-quantum we-0D kuya ku-3D Carbon Skeleton, okokuqala, ngokuya ngezinhlobo ezahlukahlukene ze-carbon matrix, izindlela ezihambisanayo ze-hybrid, amaphepha afingqiwe futhi iqhathani. Okwesibili, ubudlelwane bokusebenza kwe-XD / 2D-Carbon / Mxene Hetholfuction kuqhathaniswa ngokuya nge-synthesis-performance-performance logic. Kususelwa kumugqa wesikhathi we-multi-ntathu matrix yekhabhoni kanye ne-Mnene Complex, kusuka ku-1D CNTs Compless, i-2D Chrongts Assembwe, kuya kamuva nje, ososayensi bangakwazi ukucaciswa qonda umthambo wokuhlola. Kusuka kwinani lezindatshana ezishicilelwe, akunzima ukubona ukuthi inani lamaphepha okucwaninga ahlobene nezinto zokwenza unyaka, phakathi kwalo, ingxenye yokucwaninga nge-Mxene-based carbon composites nayo iya phezulu nangaphezulu, futhi Okubaluleke kakhulu, kuningi futhi kuningi ngokwengeziwe ngokwezinhlobo, okuyenelisa inqubekela phambili yocwaningo ye-Mxene. Ekugcineni, inqubekelaphambili yocwaningo yezihlanganisi zekhabhoni ezisekelwe kwikhabhoni yafushaniswa futhi ukuqondiswa kocwaningo ngekusasa kwaqedwa.
