Ukusetyenziswa kwe-Fe3O4 nanoparticles:

I-catalyst:
Amasuntswana e-Fe3O4 asetyenziswa njenge-catalysts kwi-industrial reactions ezininzi, ezifana nokuveliswa kwe-NH3 (indlela yokuvelisa i-Haber ammonia), i-high-temperature yokugqithiswa kwamanzi-gas reaction reaction kunye negesi yendalo desulfurization reaction. Ngenxa yobukhulu obuncinci be-nanoparticles ye-Fe3O4, indawo enkulu yendawo ethile, kunye nokungahambi kakuhle kwendawo ye-nanoparticles, amanyathelo angalinganiyo e-athomu ayenziwa, okwandisa indawo yokuqhagamshelana neekhemikhali. Ngexesha elifanayo, iinqununu ze-Fe3O4 zisetyenziselwa njenge-carrier kunye ne-catalyst components zifakwe phezu kobuso beengqungquthela ukulungiselela i-ultra-fine catalyst particles kunye ne-core-shell structure, engagcini kuphela ukusebenza okuphezulu kwe-catalytic ye-catalyst, kodwa yenza i-catalyst ibe lula ukuyirisayikilisha. Ngoko ke, iinqununu ze-Fe3O4 zisetyenziswe ngokubanzi kuphando lweenkxaso ze-catalyst.

Ushicilelo ngemagnethi:
Olunye usetyenziso olubalulekileyo lwe-nano-Fe3O4 i-particle magnetic kukwenza izinto zokurekhoda magnetic. I-Nano Fe3O4 ngenxa yobukhulu bayo obuncinci, isakhiwo sayo samagnetic sitshintsha ukusuka kwi-multi-domain ukuya kwi-domain-single-domain, kunye nokunyanzeliswa okuphezulu kakhulu, okusetyenziswe njengento yokurekhoda kwamagnetic kunokuphucula kakhulu umlinganiselo we-signal-to-noise, ukuphucula umgangatho womfanekiso, kwaye unokufikelela. ulwazi oluphezulu lokurekhoda ukuxinana. Ukuze ufezekise umphumo ongcono wokurekhoda, iinqununu ze-nano-Fe3O4 kufuneka zibe nokunyanzeliswa okuphezulu kunye ne-magnetization eseleyo, ubungakanani obuncinci, ukuxhathisa kwe-corrosion, ukumelana nokuxhatshazwa kunye nokulungelelanisa utshintsho lobushushu.

Ukufunxa kwiMicrowave:
I-Nanoparticles ineempawu ze-optical ezingafumanekiyo kwizinto eziqhelekileyo zobuninzi ngenxa yesiphumo sobukhulu obuncinci, njenge-optical nonlinearity, kunye nokulahlekelwa kwamandla ngexesha lokutshatyalaliswa kokukhanya kunye nokukhanya okukhanyayo, okuxhomekeke kakhulu kubukhulu be-nanoparticles. Uphononongo lubonise ukuba ukusebenzisa iimpawu ezikhethekileyo ze-nanoparticles ukulungiselela izinto ezahlukeneyo ze-optical ziya kusetyenziswa ngokubanzi kubomi bemihla ngemihla kunye nemimandla ye-high-tech. Uphando lwangoku ngalo mba lusekwinqanaba lebhubhoratri. Isiphumo sobungakanani be-quantum ye-nano-particles yenza ukuba kube yinto eluhlaza okwesibhakabhaka yokufunxa ukukhanya kobude obuthile. Ukufunxwa kokukhanya kwamaza ahlukeneyo nge-nano-particle powder kunento yokwandisa. Ngenxa yokungena kwayo kwimagnethi ephezulu, i-Fe3O4 i-nanopowders yamagnetic ingasetyenziswa njengohlobo lwezinto ezifunxa i-ferrite, ezisetyenziswa kwi-microwave absorption.

Ukususwa kwe-Adsorption yongcoliseko lwamanzi kunye nokubuyiselwa kwentsimbi exabisekileyo:
Ngokuphuhliswa ngokukhawuleza kwezoshishino, ukungcoliseka kwamanzi okuhambayo kuye kwanda ngakumbi nangakumbi, ngakumbi ii-ion zetsimbi kumzimba wamanzi, ukungcola okunzima ukuthotywa kwezinto eziphilayo, njl., ezingelula ukuhlukana emva kokunyanga. Ukuba i-magnetic adsorption material isetyenzisiwe, kunokuba lula uKwahlula. Uphononongo lufumene ukuba xa i-Fe3O4 i-nanocrystals isetyenziselwa ukubhengeza i-ion zensimbi ezihloniphekileyo ezifana ne-Pd2+, i-Rh3+, i-Pt4+ kwi-hydrochloric acid distillate, umthamo ophezulu we-adsorption we-Pd 2+ ngu-0.103mmol·g -1 kunye nomthamo omkhulu we-adsorption we-Rh3+ 0.149mmol · g -1, ubuninzi be-adsorption umthamo we I-Pt4+ yi-0.068mmol·g-1. Ke ngoko, iinanocrystals zemagnethi zeFe3O4 zikwasisisombululo esilungileyo se-adsorbent yentsimbi exabisekileyo, ebaluleke kakhulu ekuhlaziyweni kweentsimbi ezixabisekileyo.
