Ngaphezulu kwama-MXene we-stoichiometric angu-30 asevele ahlanganiswa, nama-MXenes esixazululo esiqinile esingeziwe.I-MXene ngayinye inezici ezihlukile zokubuka, ze-elekthronikhi, ezibonakalayo, namakhemikhali, okuholela ekutheni zisetshenziswe cishe kuyo yonke imikhakha, kusukela ku-biomedicine kuya endaweni yokugcina amandla e-electrochemical.Umsebenzi wethu ugxile ekuhlanganisweni kwezigaba ezihlukene ze-MAX kanye nama-MXenes, okuhlanganisa ukuqanjwa nezakhiwo ezintsha, ezihlanganisa wonke amakhemistri we-M, A, no-X, nangokusebenzisa zonke izindlela ezaziwayo zokuhlanganisa i-MXene.Okulandelayo ezinye zezinkomba ezithile esizilandelayo:
1. Ukusebenzisa ama-M-chemistries amaningi
Ukukhiqiza ama-MXene anezinto eziguqulekayo (M'yM”1-y)n+1XnTx, ukuzinzisa izakhiwo ezingakaze zibe khona ngaphambili (M5X4Tx), futhi ngokuvamile kunqunywe umthelela wekhemikhali ezimpahleni ze-MXene.
2. Ukuhlanganiswa kwe-MXenes kusuka ezigabeni ezingezona ze-aluminium MAX
Ama-MXenes ikilasi lezinto ze-2D ezihlanganiswe ukuqoshwa kwamakhemikhali kwe-elementi engu-A ngezigaba ezingu-MAX.Selokhu atholakala eminyakeni eyi-10 edlule, inani lama-MXenes ahlukile akhule kakhulu ukuze afake ama-MnXn-1 amaningi (n = 1,2,3,4, noma 5), izixazululo zawo eziqinile (eziyaliwe futhi ziphazamisekile), kanye nezikhala zezikhala.Ama-MXene amaningi akhiqizwa kusukela ku-aluminium MAX izigaba, nakuba kube khona imibiko embalwa ye-MXenes ekhiqizwa kwezinye izakhi ze-A (isb, i-Si ne-Ga).Sifuna ukunweba umtapo wezincwadi wama-MXenes afinyelelekayo ngokwakha izivumelwano zokuhlanganisa (isb, i-asidi exutshiwe, usawoti oncibilikisiwe, njll.) kwezinye izigaba ezingezona ze-aluminium MAX ezisiza ukucwaninga kwama-MXenes amasha kanye nezakhiwo zawo.
3. Etching kinetics
Sizama ukuqonda i-kinetics ye-etching, ukuthi i-etching chemistry ithinta kanjani izakhiwo ze-MXene, nokuthi singalusebenzisa kanjani lolu lwazi ukuze sithuthukise ukuhlanganiswa kwe-MXenes.
4. Izindlela ezintsha zokususa i-MXenes
Sibheka izinqubo ezinwebekayo ezivumela ukuthi kube nokwenzeka kwe-MXenes' delamination.
