Kushandiswa kweFe3O4 nanoparticles:

catalyst:
Fe3O4 zvimedu zvinoshandiswa sezvinokonzeresa mune akawanda maindasitiri maitiro, akadai sekugadzirwa kweNH3 (Haber ammonia nzira yekugadzira), yakakwirira-tembiricha yemvura-gasi kutumira reaction uye gasi rechisikigo desulfurization reaction.Nekuda kwehukuru hudiki hweFe3O4 nanoparticles, iyo yakakura chaiyo nzvimbo, uye hurombo hwepamusoro kutsvedzerera kwe nanoparticles, nhanho dzeatomu dzisina kuenzana dzinoumbwa, izvo zvinowedzera kusangana kwenzvimbo yekuchinja kwemakemikari.Panguva imwecheteyo, Fe3O4 zvimedu zvinoshandiswa semutakuri uye zvikamu zvinokonzeresa zvakaputirwa pamusoro pezvimedu kuti zvigadzirire ultra-fine catalyst particles ine core-shell structure, iyo inongochengetedza yakakwirira catalytic performance ye catalyst, asi zvakare inoita kuti iyo catalyst ive nyore kudzokorodza.Nokudaro, Fe3O4 zvidimbu zvakashandiswa zvakanyanya mukutsvakurudza kwezvitsigiro zvinotsigira.

Magnetic kurekodha:
Kumwe kushandiswa kwakakosha kwenano-Fe3O4 magineti particles ndeyekugadzira magineti ekurekodha zvinhu.Nano Fe3O4 nekuda kwehukuru hwayo, magineti ayo anoshanduka kubva kune akawanda-domain kuenda kune imwechete-domain, ine yakanyanya kumanikidza, inoshandiswa semagineti yekurekodha zvinhu inogona kuvandudza zvakanyanya chiratidzo-ku-ruzha reshiyo, kuvandudza chimiro chemufananidzo, uye inogona kubudirira. high information kurekodha density.Kuti uwane yakanakisa kurekodha mhedzisiro, nano-Fe3O4 zvimedu zvinofanirwa kunge zvine yakakwirira coercivity uye yakasara magineti, diki saizi, corrosion resistance, friction resistance uye kuenderana nekushanduka kwekushisa.

Microwave absorption:
Nanoparticles ine optical properties iyo isingawaniki mune zvakajairwa zvinhu zvakawanda nekuda kwehukuru hukuru hunoita, senge optical nonlinearity, uye kurasikirwa kwesimba panguva yekunwa kwechiedza uye kupenya kwechiedza, izvo zvinoenderana zvakanyanya nehukuru hwe nanoparticles.Zvidzidzo zvakaratidza kuti kushandisa yakakosha optical properties ye nanoparticles kugadzirira zvakasiyana-siyana optical zvinhu zvichashandiswa zvakanyanya muhupenyu hwezuva nezuva uye high-tech minda.Tsvagiridzo yazvino pamusoro pechinhu ichi ichiri muchikamu cherabhoritari.Iyo quantum saizi mhedzisiro yenano-particles inoita kuti ive yebhuruu shanduko chiitiko chekunyudza kwechiedza cheimwe wavelength.Kutorwa kwechiedza cheavelengths akasiyana-siyana ne nano-particle powder kune chiitiko chinowedzera.Nekuda kwekukwirira kwayo kwemagineti, Fe3O4 magineti nanopowder inogona kushandiswa senge rudzi rwe ferrite inonwisa zvinhu, iyo inoshandiswa mukunyudza microwave.

Adsorption kubviswa kwezvinosvibisa mvura uye kudzoreredza simbi yakakosha:
Nekukurumidza kukura kwemaindasitiri, kusvibiswa kwemvura kunoperekedza kwakawedzera zvakanyanya, kunyanya ioni dzesimbi mumvura yemvura, zvakaoma-ku-degrade organic pollutants, nezvimwewo, izvo zvisiri nyore kuparadzanisa mushure mekurapa.Kana iyo magineti adsorption zvinhu ikashandiswa, zvinogona kuve nyore Kupatsanura.Zvidzidzo zvakaona kuti kana Fe3O4 nanocrystals inoshandiswa kushambadza maion simbi ane mbiri akadai sePd2+, Rh3+, Pt4+ muhydrochloric acid distillate, iyo yakanyanya adsorption kugona kwePd 2+ i0.103mmol·g -1 uye yakakura adsorption kugona kweRh3+ 0.149mmol·g -1, iyo yakanyanya adsorption huwandu hwePt4+ i0.068mmol·g-1.Naizvozvo, magineti Fe3O4 nanocrystals zvakare mhinduro yakanaka yakakosha simbi adsorbent, iyo yakakosha zvikuru pakudzokororwa kwesimbi dzinokosha.
