Incazelo:
Ukusetshenziswa kwe-Fe3O4 nanoparticles:
i-catalyst:
Izinhlayiya ze-Fe3O4 zisetshenziswa njengama-catalysts ekuphenduleni okuningi kwezimboni, njengokukhiqizwa kwe-NH3 (indlela yokukhiqiza i-Haber ammonia), ukusabela kokudlulisa amanzi-igesi lokushisa eliphezulu kanye nokusabela kwegesi yemvelo desulfurization. Ngenxa yobukhulu obuncane be-Fe3O4 nanoparticles, indawo enkulu ethize, kanye nobushelelezi bobuso obumpofu be-nanoparticles, kwakheka izinyathelo ze-athomu ezingalingani, okwandisa indawo yokuxhumana yokusabela kwamakhemikhali. Ngesikhathi esifanayo, izinhlayiya ze-Fe3O4 zisetshenziswa njengesithwali futhi izingxenye ze-catalyst ziboshwe ebusweni bezinhlayiya ukuze kulungiswe izinhlayiya ze-catalyst ze-ultra-fine ngesakhiwo se-core-shell, esingagcini nje ngokugcina ukusebenza okuphezulu kwe-catalytic ye-catalyst, kodwa futhi yenza i-catalyst ibe lula ukuyigaya kabusha. Ngakho-ke, izinhlayiya ze-Fe3O4 zisetshenziswe kabanzi ocwaningweni lwama-catalyst support.
Ukuqoshwa kwamagnetic:
Okunye ukusetshenziswa okubalulekile kwezinhlayiya kazibuthe ze-nano-Fe3O4 ukwenza izinto zokuqopha kazibuthe. I-Nano Fe3O4 ngenxa yobukhulu bayo obuncane, ukwakheka kwayo kazibuthe kuyashintsha kusuka kusizinda esiningi kuya esizindeni esisodwa, ngokuphoqelelwa okuphezulu kakhulu, okusetshenziswe njengento yokurekhoda kazibuthe ingathuthukisa kakhulu isilinganiso sesignali-kuya-nomsindo, ithuthukise ikhwalithi yesithombe, futhi ingafinyelela. ulwazi oluphezulu lokuqopha ukuminyana. Ukuze kuzuzwe umphumela ongcono kakhulu wokuqopha, izinhlayiya ze-nano-Fe3O4 kumele zibe nokuphoqelela okuphezulu kanye ne-magnetization esele, usayizi omncane, ukumelana nokugqwala, ukumelana nokungqubuzana nokuzivumelanisa nokushintsha kwezinga lokushisa.
Ukumuncwa kwe-microwave:
I-Nanoparticles inezinto ezibonakalayo ezingatholakali ezintweni ezivamile zobuningi ngenxa yomphumela wesayizi omncane, njengokungabonakali kwe-optical, nokulahlekelwa kwamandla ngesikhathi sokumunca ukukhanya nokubonakaliswa kokukhanya, okuncike kakhulu kusayizi we-nanoparticles. Ucwaningo luye lwabonisa ukuthi ukusebenzisa izakhiwo ezikhethekile ze-optical ze-nanoparticles ukulungisa izinto ezihlukahlukene ze-optical kuzosetshenziswa kabanzi ekuphileni kwansuku zonke kanye nezinkambu zobuchwepheshe obuphezulu. Ucwaningo lwamanje mayelana nalesi sici lusasesigabeni saselabhorethri. Umthelela wesayizi we-quantum wezinhlayiya ze-nano uwenza kube isenzakalo sokushintsha okuluhlaza okwesibhakabhaka sokumunca ukukhanya kobude obuthile beza. Ukumuncwa kokukhanya kwamaza ahlukahlukene nge-nano-particle powder kunento enwebekayo. Ngenxa yokufinyeleleka kwayo okukhulu kazibuthe, i-Fe3O4 nanopowder kazibuthe ingasetshenziswa njengohlobo lwezinto ezimunca i-ferrite, ezisetshenziswa ekumunceni i-microwave.
Ukususwa kwe-Adsorption kokungcola kwamanzi kanye nokubuyiselwa kwensimbi eyigugu:
Ngokuthuthuka okusheshayo kwezimboni, ukungcoliswa kwamanzi okuhambisana nakho kuye kwaba nzima nakakhulu, ikakhulukazi i-ion yensimbi emanzini, ukungcola okunzima ukwehlisa izinto eziphilayo, njll, okungelula ukuhlukana ngemva kokwelashwa. Uma kusetshenziswa okubalulekile kwe-magnetic adsorption, kungaba lula Ukuhlukanisa. Ucwaningo luye lwathola ukuthi uma i-Fe3O4 nanocrystals isetshenziselwa ukukhangisa ama-ion ensimbi ahloniphekile njenge-Pd2+, Rh3+, Pt4+ ku-hydrochloric acid distillate, umthamo omkhulu we-adsorption we-Pd 2+ ngu-0.103mmol·g -1 kanye nomthamo omkhulu wokukhangisa we-Rh3+ 0.149mmol·g -1, umthamo omkhulu we-adsorption we I-Pt4+ ingu-0.068mmol·g-1. Ngakho-ke, ama-nanocrystals azibuthe we-Fe3O4 nawo ayisixazululo esihle i-adsorbent yensimbi eyigugu, ebaluleke kakhulu ekugayweni kabusha kwezinsimbi eziyigugu.
Isimo Sesitoreji:
I-Fe3O4 nanoparticles kufanele igcinwe endaweni evaliwe, gwema ukukhanya, indawo eyomile. Isitoreji sezinga lokushisa kwegumbi SILUNGILE.
