Zomangamanga za 3D zokhala ndi porous Ti3C2 MXene kuphatikiza ndi NiCoP bimetallic phosphide nanoparticles

Posachedwapa, gulu lofufuza la Longwei Yin la ku yunivesite ya Shandong linasindikiza nkhani Energy & Environmental Science, mutuwu ndi Alkali-induced 3D crinkled porous Ti3C2 MXene architectures pamodzi ndi NiCoP bimetallic phosphide nanoparticles monga anode for high-performance sodium-ion mabatire.

Kuti apititse patsogolo kukhazikika kwapangidwe ndikuwongolera ma electrochemical reaction kinetics a anodes a sodium ion mabatire (SIBs), amapanga njira yatsopano yolumikizira ma NiCoP bimetallic phosphide nanoparticles okhala ndi alkali-induced 3D olumikizana ndi porous Ti3C2 MXenes ngati anodi a ma SIBs ochita bwino kwambiri. .

The interconnected 3D Ti3C2 crinkled zomangamanga akhoza kukhazikitsa 3D conductive maukonde, wochuluka pores lotseguka ndi lalikulu pamwamba dera, amene amapereka 3D conductive khwalala ndi zosatsekeredwa njira kwa mofulumira mlandu kutengerapo ndondomeko ndi posungira electrolyte, ndipo amalumikizana kwambiri pakati pa elekitirodi ndi. electrolyte.Mapangidwe apadera a MXene amatha kulekerera kukula kwa voliyumu ndikuletsa kuphatikizika ndi kupukutira kwa ma nanoparticles a NiCoP panthawi ya Na+ kuika / kuchotsa.NiCoP bimetallic phosphide ili ndi malo ochulukirapo a redox reaction, ma conductivity apamwamba amagetsi komanso kutsika kwamphamvu kosinthira.The synergistic zotsatira pakati pa zigawo za NiCoP ndi MXene Ti3C2 ndi mkulu structural bata ndi electrochemical ntchito kumabweretsa kwambiri electrochemical ntchito, kusunga mphamvu yeniyeni ya 261.7 mA hg.^-1pa kachulukidwe panopa 1 A g^-1kwa 2000 zozungulira.Njira yamakono yamu situNjira ya phosphization ndi kuphatikiza ma phosphides okhala ndi 3D Ti3C2 yokhotakhota zitha kupititsidwa ku maelekitirodi ena amtundu wa zida zosungiramo mphamvu zogwira ntchito kwambiri.
