MAX Mehato le MXenes Synthesis

Ho se ho entsoe li-MXenes tse fetang 30 tsa stoichiometric, tse nang le li-MXenes tse ngata tsa tharollo e tiileng. MXene e 'ngoe le e' ngoe e na le lisebelisoa tse ikhethang tsa optical, elektronike, 'mele le lik'hemik'hale, e leng se etsang hore li sebelisoe hoo e batlang e le tšimo e' ngoe le e 'ngoe, ho tloha ho biomedicine ho ea polokelo ea matla a electrochemical. Mosebetsi oa rona o tsepamisitse maikutlo ho kopanngoeng ha mekhahlelo e fapaneng ea MAX le MXenes, ho kenyeletsoa liqapi le libopeho tse ncha, tse amang lik'hemik'hale tsohle tsa M, A, le X, le ka ho sebelisa mekhoa eohle e tsebahalang ea MXene. Tse latelang ke tse ling tsa litsela tseo re li latelang:

1. Ho sebelisa li-M-chemistries tse ngata
Ho hlahisa li-MXenes tse nang le thepa e ka sebelisoang (M'yM”1-y)n+1XnTx, ho tsitsisa mehaho e e-s'o ka e e-ba teng pele (M5X4Tx), 'me ka kakaretso ho fumana phello ea k'hemistri ho thepa ea MXene.

2. Synthesis ea MXenes ho tloha mekhahlelong e seng ea aluminium MAX
MXenes ke sehlopha sa lisebelisoa tsa 2D tse entsoeng ka lik'hemik'hale tsa A element ka mekhahlelo ea MAX. Ho tloha ha ba sibolloa lilemong tse 10 tse fetileng, palo ea li-MXenes tse ikhethileng e eketsehile haholo ho kenyelletsa MnXn-1 e mengata (n = 1,2,3,4, kapa 5), ​​litharollo tsa bona tse tiileng (tse laetsoeng le tse sa sebetseng), le li-solid tsa sekheo. Boholo ba MXenes bo hlahisoa ho tloha aluminium MAX mekhahlelo, le hoja ho bile le litlaleho tse 'maloa tsa MXenes tse hlahisoang ho tsoa ho likarolo tse ling tsa A (mohlala, Si le Ga). Re batla ho holisa laeborari ea li-MXenes tse fumanehang ka ho etsa li-protocol tsa etching (mohlala, acid e tsoakiloeng, letsoai le qhibilihisitsoeng, joalo-joalo) bakeng sa mekhahlelo e meng eo e seng ea aluminium MAX e thusang ho ithuta li-MXenes tse ncha le thepa ea tsona.

3. Etching kinetics
Re leka ho utloisisa kinetics ea etching, hore na chemistry ea etching e ama thepa ea MXene joang, le hore na re ka sebelisa tsebo ena joang ho ntlafatsa motsoako oa MXenes.

4. Mekhoa e mecha ea delamination ea MXenes
Re shebile lits'ebetso tse scalable tse lumellang monyetla oa hore MXenes delamination e be teng.
