Uphuhliso lwamandla acocekileyo nahlaziyekayo sisicwangciso esingundoqo sophuhliso lwentlalo noqoqosho lwelizwe lethu.Kuwo onke amanqanaba obuchwepheshe bamandla amatsha, ukugcinwa kwamandla e-electrochemical kunendawo ebaluleke kakhulu, kwaye ikwangumba oshushu kuphando lwesayensi lwangoku.Njengohlobo olutsha lwezixhobo zokuqhuba ulwakhiwo olunamacala amabini, ukusetyenziswa kwegraphene kunokubaluleka okubalulekileyo kunye namandla amakhulu ophuhliso kule ntsimi.

I-graphene sesinye sezona zixhobo zichaphazelekayo.Ulwakhiwo lwayo lwenziwe ngee-symmetrical, ii-lettice ezingaphantsi kwendlwane.I-Doping ngee-athom ezingafaniyo yindlela ebalulekileyo yokuqhawula isakhiwo se-symmetric kunye nokulungelelanisa iimpawu zayo zomzimba.Iiathom zenitrojeni zinobungakanani obusondeleyo kobo beeathom zekhabhoni kwaye kulula ukuba zifakwe kwilathisi yegraphene.Ngoko ke, i-nitrogen doping idlala indima ebalulekileyo kuphando lwezixhobo zegraphene.Ukutshintshwa kwe-doping kungasetyenziselwa ukutshintsha iimpawu ze-elektroniki zegraphene ngexesha lenkqubo yokukhula.

      IGraphene ifakwe initrogeninokuvula i-gap yebhendi yamandla kwaye ilungelelanise uhlobo lwe-conductivity, itshintshe isakhiwo se-elektroniki, kwaye yandise ukuxinwa kwe-carrier carrier, ngaloo ndlela iphucula ukuqhuba kunye nokuzinza kwegraphene.Ukongeza, ukuqaliswa kwezakhiwo ze-athomu ezine-nitrogen kwigridi yekhabhoni yegraphene kunokunyusa iindawo ezisebenzayo ezibhengezwe kumphezulu wegraphene, ngaloo ndlela kuphuculwe intsebenziswano phakathi kwamasuntswana esinyithi kunye negraphene.Ke ngoko, ukusetyenziswa kwe-nitrogen-doped graphene kwizixhobo zokugcina amandla kunokusebenza okuphezulu kakhulu kwe-electrochemical, kwaye kulindeleke ukuba ibe yinto ephezulu yokusebenza kwe-electrode.Uphando olukhoyo lukwabonisa ukuba i-nitrogen-doped graphene inokuphucula kakhulu iimpawu zesakhono, intlawulo ekhawulezileyo kunye nokukhupha amandla kunye nobomi bomjikelezo wezinto zokugcina amandla, kwaye inamandla amakhulu okusebenza kwindawo yokugcina amandla.

Igraphene ene-nitrogen

I-Nitrogen-doped graphene yenye yeendlela ezibalulekileyo zokuqonda ukusebenza kwegraphene, kwaye idlala indima ephambili ekwandiseni imimandla yesicelo.I-graphene ye-N-doped inokuphucula kakhulu iimpawu zomthamo, ukuhlawuliswa ngokukhawuleza kunye nokukhupha amandla kunye nobomi bomjikelezo wezinto zokugcina amandla, kwaye inamandla amakhulu okusebenza kwiinkqubo zokugcina amandla ekhemikhali ezifana ne-supercapacitors, i-lithium ion, i-lithium sulphur kunye neebhetri zomoya ze-lithium.

Ukuba unomdla kwenye igraphene esebenzayo, nceda ungalibazisi ukuqhagamshelana nathi.Inkonzo eyongezelelweyo yokwenza ngokwezifiso ibonelelwa nguHongwu Nano.
