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 eshiyekileyo, ubungakanani obuncinci, ukuxhathisa ukubola, ukuxhathisa ukuxhatshazwa 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 neendawo eziphezulu zobuchwepheshe.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-nanopowder magnetic ingasetyenziswa njengohlobo lwezinto ezifunxa i-ferrite, ezisetyenziselwa ukufunxa kwi-microwave.

Ukususwa kwe-Adsorption yongcoliseko lwamanzi kunye nokubuyiselwa kwentsimbi exabisekileyo:
Ngokukhula ngokukhawuleza kwezoshishino, ukungcoliseka kwamanzi okuhamba kunye nokubi ngakumbi, 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 nanocrystals isetyenziselwa ukubhengeza i-ion zetsimbi 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-Pt4+ ngu-0.068mmol·g-1.Ke ngoko, iinanocrystals zemagnethi zeFe3O4 zikwasisisombululo esilungileyo se-adsorbent yentsimbi exabisekileyo, ebaluleke kakhulu ekuhlaziyweni kweentsimbi ezixabisekileyo.
