3D crinkled porous Ti3C2 MXene hale kiʻi i hui pū ʻia me NiCoP bimetallic phosphide nanoparticles

I kēia mau lā, ua paʻi ka hui noiʻi o Longwei Yin mai ke Kulanui ʻo Shandong i kahi ʻatikala ma Energy & Environmental Science, ʻo ke poʻo inoa ʻo Alkali-induced 3D crinkled porous Ti3C2 MXene architectures i hui pū ʻia me NiCoP bimetallic phosphide nanoparticles ma ke ʻano he anodes no nā pākahi sodium-ion kiʻekiʻe.

No ka hoʻonui ʻana i ka paʻa o ke kūkulu ʻana a me ka hoʻomaikaʻi ʻana i nā kinetics hopena electrochemical maikaʻi ʻole o nā anodes no nā ʻāpana sodium ion (SIBs), hoʻomohala lākou i kahi hoʻolālā hou e hoʻohui i nā nanoparticles bimetallic phosphide NiCoP me ka alkali-induced 3D interconnected crinkled porous Ti3C2 MXenes i anodes no nā SIBs kiʻekiʻe. .

Hiki ke hoʻokumu ʻia nā hale hana 3D Ti3C2 i hoʻopaʻa ʻia i kahi pūnaewele conductive 3D, nui nā pores ākea a me kahi ākea ākea, kahi e hāʻawi ai i kahi ala ala alakaʻi 3D a me nā ala i wehe ʻole ʻia no ke kaʻina hana hoʻololi wikiwiki a no ka mālama ʻana i nā electrolyte, a hoʻopili kokoke loa ma waena o ka electrode a electrolyte.Hiki i ka hana MXene kū hoʻokahi ke ʻae i ka hoʻonui ʻana i ka leo a pale i ka hōʻuluʻulu ʻana a me ka pulverization o nā nanoparticles NiCoP i ka wā o ka hoʻokomo ʻana o Na + / kaʻina hana.Loaʻa i ka NiCoP bimetallic phosphide nā wahi ʻoi aku ka maikaʻi o ka redox reaction, ʻoi aku ka kiʻekiʻe o ka uila a me ka haʻahaʻa haʻahaʻa.ʻO ka hopena synergistic ma waena o nā mea o NiCoP a me MXene Ti3C2 me ke kūpaʻa kiʻekiʻe a me ka hana electrochemical alakaʻi i ka hana electrochemical maikaʻi loa, e mālama ana i kahi mana kikoʻī o 261.7 mA hg^-1i ka nui o keia manawa o 1 A g^-1no 2000 pōʻaiapuni.ʻO ka hoʻolālā o kēia manawa o kahiin situʻO ke ala phosphization a me ka hoʻohui ʻana i nā phosphides me 3D Ti3C2 crinkled hiki ke hoʻonui ʻia i nā electrodes hou no nā mea mālama ikehu hana kiʻekiʻe.
