ʻOi aku ma mua o 30 stoichiometric MXenes ua hoʻohui ʻia, me nā MXenes paʻa paʻa ʻē aʻe.Loaʻa i kēlā me kēia MXene nā waiwai optical, uila, kino, a me nā mea kemika, e alakaʻi ana iā lākou e hoʻohana ʻia ma nā wahi āpau, mai biomedicine a hiki i ka mālama ʻana i ka ikehu electrochemical.Hoʻopili kā mākou hana i ka synthesis o nā ʻano MAX like ʻole a me nā MXenes, me nā haku mele a me nā hale hou, e hoʻopili ana i nā kemika M, A, a me X, a ma o ka hoʻohana ʻana i nā ʻano hoʻohālikelike MXene synthesis āpau.Eia kekahi mau kuhikuhi kiko'ī a mākou e hahai nei:
1. Ke hoʻohana nei i nā M-chemistries lehulehu
No ka hana ʻana i nā MXene me nā waiwai hiki ke hoʻopaʻa ʻia (M'yM”1-y)n+1XnTx, e hoʻopaʻa i nā hale i loaʻa ʻole ma mua (M5X4Tx), a e hoʻoholo maʻamau i ka hopena o ke kemika ma nā waiwai MXene.
2. Hoʻohui i nā MXenes mai nā ʻāpana MAX ʻole alumini
ʻO MXenes kahi papa o nā mea 2D i hoʻohui ʻia e ke kiʻi kemika o ka mea A ma nā pae MAX.Mai ko lākou ʻike ʻia ʻana ma mua o 10 mau makahiki i hala aku nei, ua ulu nui ka helu o nā MXenes ʻokoʻa e hoʻokomo i nā MnXn-1 (n = 1,2,3,4, a i ʻole 5), ko lākou mau hāʻina paʻa (kau ʻia a hoʻoponopono ʻia), a me nā paʻa hakahaka.Hana ʻia ka hapa nui o nā MXenes mai nā ʻāpana alumini MAX, ʻoiai aia kekahi mau hōʻike o MXenes i hana ʻia mai nā mea A ʻē aʻe (e laʻa, Si a me Ga).Ke ʻimi nei mākou e hoʻonui i ka waihona o nā MXenes hiki ke loaʻa ma o ka hoʻomohala ʻana i nā protocol etching (e laʻa, ka waikawa hui ʻia, ka paʻakai hoʻoheheʻe, a me nā mea ʻē aʻe) no nā hana MAX ʻole alumini e hoʻomaʻamaʻa i ke aʻo ʻana i nā MXenes hou a me ko lākou mau waiwai.
3. Etching kinetics
Ke ho'āʻo nei mākou e hoʻomaopopo i nā kinetics o ka etching, pehea e pili ai ka chemistry etching i nā waiwai MXene, a pehea e hiki ai iā mākou ke hoʻohana i kēia ʻike e hoʻonui i ka synthesis o MXenes.
4. Nā ala hou i ka delamination o MXenes
Ke nānā nei mākou i nā kaʻina hana scalable e ʻae ai i ka hiki ke hoʻopau ʻia ʻo MXenes.
