Tšebeliso ea Fe3O4 nanoparticles:
catalyst:
Likaroloana tsa Fe3O4 li sebelisoa e le li-catalysts liketsong tse ngata tsa indasteri, joalo ka tlhahiso ea NH3 (mokhoa oa tlhahiso ea Haber ammonia), karabelo e phahameng ea mocheso oa phetisetso ea khase ea metsi le khase ea tlhaho ea desulfurization.Ka lebaka la boholo bo bonyenyane ba Fe3O4 nanoparticles, sebaka se seholo se khethehileng sa holim'a metsi, le boreleli bo bobe ba nanoparticles, mehato e sa lekaneng ea athomo e thehoa, e leng ho eketsang sebaka sa ho kopana bakeng sa lik'hemik'hale.Ka nako e ts'oanang, likaroloana tsa Fe3O4 li sebelisoa e le sesebelisoa 'me likaroloana tsa catalyst li koahetsoe holim'a likaroloana ho lokisa likaroloana tsa li-catalyst tse nang le li-core-shell, tse sa bolokeng feela ts'ebetso e phahameng ea catalytic ea catalyst, empa hape e etsa hore catalyst e be bonolo ho e sebelisa hape.Ka hona, likaroloana tsa Fe3O4 li sebelisitsoe haholo lipatlisisong tsa li-catalyst supports.
Rekoto ea Magnetic:
Tšebeliso e 'ngoe ea bohlokoa ea nano-Fe3O4 magnetic particles ke ho etsa lisebelisoa tsa ho rekota tsa magnetic.Nano Fe3O4 ka lebaka la boholo ba eona bo nyane, sebopeho sa eona sa matla a khoheli se fetoha ho tloha ho li-domain tse ngata ho ea ho se le seng, se nang le ts'ebetso e phahameng haholo, e sebelisoang e le thepa ea ho rekota ea matla a khoheli e ka ntlafatsa haholo karo-karolelano ea lerata, ho ntlafatsa boleng ba setšoantšo, 'me e ka finyella. phahameng data rekota segokanyipalo.E le hore u finyelle phello e ntle ka ho fetisisa ea ho rekota, likaroloana tsa nano-Fe3O4 li tlameha ho ba le coercivity e phahameng le masala a magnetization, boholo bo fokolang, ho hanyetsa kutu, ho hanyetsa ho ferekanngoa le ho ikamahanya le liphetoho tsa mocheso.
Ho kenngoa ha microwave:
Li-nanoparticles li na le lisebelisoa tsa optical tse sa fumaneheng ka thepa e tloaelehileng ea bongata ka lebaka la phello e nyenyane ea boholo, e kang optical nonlinearity, le tahlehelo ea matla nakong ea ho kenngoa ha leseli le ho bonahatsa leseli, tse itšetlehileng haholo ka boholo ba nanoparticles.Liphuputso li bontšitse hore ho sebelisa lisebelisoa tse khethehileng tsa optical tsa nanoparticles ho lokisetsa lisebelisoa tse sa tšoaneng tsa optical li tla sebelisoa haholo bophelong ba letsatsi le letsatsi le masimo a theknoloji e phahameng.Patlisiso ea hajoale mabapi le ntlha ena e ntse e le mothating oa laboratori.Phello ea boholo ba quantum ea nano-particles e etsa hore e be phetoho e putsoa bakeng sa ho monya ha leseli la leqhubu le itseng.Ho monya ha leseli la maqhubu a fapaneng a maqhubu ka phofo ea nano-particle ho na le ts'ebetso e atolohang.Ka lebaka la matla a eona a matla a makenete, Fe3O4 magnetic nanopowders e ka sebelisoa e le mofuta oa thepa e monyang ferrite, e sebelisoang ho monya ka microwave.
Ho tlosoa ha adsorption ea litšila tsa metsi le ho hlaphoheloa ha tšepe ea bohlokoa:
Ka tsoelo-pele e potlakileng ea indasteri, tšilafalo ea metsi e tsamaeang le eona e fetohile e tebileng le ho feta, haholo-holo li-ion tsa tšepe 'meleng oa metsi, ho thata ho senya litšila tse phelang, joalo-joalo, tseo ho seng bonolo ho li arola ka mor'a phekolo.Haeba ho sebelisoa thepa ea magnetic adsorption, ho ka ba bonolo Karohano.Liphuputso li fumane hore ha Fe3O4 nanocrystals e sebelisoa ho adsorb li-ion tsa tšepe tse ntle tse kang Pd2+, Rh3+, Pt4+ ka har'a hydrochloric acid distillate, tekanyo e phahameng ea adsorption bakeng sa Pd 2+ ke 0.103mmol·g -1 le matla a mangata a adsorption bakeng sa Rh3+ ke 0.149mmol·g -1, matla a mangata a adsorption bakeng sa Pt4 + ke 0.068mmol·g-1.Ka hona, magnetic Fe3O4 nanocrystals e boetse e le tharollo e ntle ea tšepe ea bohlokoa ea adsorbent, e leng ea bohlokoa haholo ho tsosolosoa ha litšepe tsa bohlokoa.
Boemo ba polokelo:
Fe3O4 nanoparticles e lokela ho bolokoa sebakeng se tiisitsoeng, qoba leseli, sebaka se omileng.Ho boloka mocheso oa kamore ho lokile.
