Anatasetitanium dioxide, eyaziwa nangokuthi i-titanium dioxide, iyinhlanganisela ekhangayo eye yakhanga isithakazelo esikhulu kwezesayensi, ezobuchwepheshe, nezimboni. Ngezakhiwo zayo eziyingqayizivele kanye nezinhlelo zokusebenza ezihlukahlukene, i-anatase titanium dioxide ibe yisihloko socwaningo olunzulu kanye nokuqanjwa okusha. Kule bhulogi, sizocubungula izici eziphawulekayo nokusetshenziswa okuhlukahlukene kwe-anatase TiO2, sicacise ukubaluleka kwayo emikhakheni ehlukahlukene.
I-Anatase TiO2 iwuhlobo lwecrystalline lwe-titanium dioxide elaziwa ngesakhiwo sayo se-tetragonal kanye nendawo ephezulu. Le nhlanganisela inezakhiwo ezinhle kakhulu ze-photocatalytic, okuyenza ibe yingxenye ebalulekile ekulungiseni imvelo kanye nobuchwepheshe bamandla avuselelekayo. Ikhono layo lokusebenzisa amandla elanga ukuze lidale ukusabela kwamakhemikhali livula indlela yentuthuko ekuhlanzeni amanzi, ekulawuleni ukungcoliswa komoya kanye nokukhiqizwa kukaphethiloli welanga.
Ngaphezu kwalokho, i-anatase titanium dioxide yaziwa ngezici zayo zokubuka futhi iyisithako esiyinhloko ekwakhekeni kwezingulube, okokumbozwa kanye nezimonyo. Inkomba yayo ephezulu ye-refractive kanye nekhono lokuvinjwa kwe-UV iyenza ilungele ukwakhiwa kokuvikela ilanga, iqinisekisa ukuvikeleka emisebeni ye-UV eyingozi. Ngaphezu kwalokho, i-anatase titanium dioxide isetshenziswa kakhulu ekukhiqizweni kombala omhlophe ukuze kuhlinzekwe ukukhanya nokufiphala emikhiqizweni ehlukahlukene yabathengi nezinto ezisetshenziswa ezimbonini.
Izakhiwo ze-elekthronikhi eziyingqayizivele zei-TiO2futhi ikwenze kube ikhandidethi elithembisayo lemishini kagesi nezinhlelo zokusebenza zokugcina amandla. Izakhiwo zayo ze-semiconducting kanye nokuhamba kwama-electron kuye kwavusa isithakazelo ekuthuthukisweni kwezinzwa ezisekelwe ku-TiO2, amaseli e-photovoltaic, namabhethri e-lithium-ion. Amandla okuhlanganisa i-anatase titanium dioxide emishinini kagesi yesizukulwane esilandelayo aphethe isithembiso sokuthuthukisa ukusebenza nokusebenza kahle kogesi kanye nokugcinwa kwamandla.
Emkhakheni wezokunakekelwa kwempilo, i-anatase titanium dioxide iye yavela njengento eguquguqukayo enezinto ezilwa namagciwane kanye nezinto zokuzihlanza. Umsebenzi wayo we-photocatalytic wehlisa isithunzi ukungcola kwezinto eziphilayo futhi wenze amagciwane ayingozi asebenze, okuwenza ube yimpahla ebalulekile eklanyweni lokuzibulala amagciwane, amasistimu okuhlanza umoya, kanye nemishini yezokwelapha. Ukusetshenziswa kwe-anatase titanium dioxide ekukhuthazeni izindawo ezihlanzekile kanye nokulwa nezinsongo zamagciwane kugqamisa ukubaluleka kwayo ekunakekelweni kwezempilo.
Ngaphezu kwalokho, i-anatase titanium dioxide idlala indima ebalulekile emkhakheni we-catalysis, yenza kube lula ukuguqulwa kwamakhemikhali kanye nezinqubo zezimboni. Amakhono ayo okusiza asetshenziswe ekukhiqizeni amakhemikhali amahle, izisusa zemvelo kanye nobuchwepheshe bamandla avuselelekayo. Ikhono le-anatase titanium dioxide ukushayela ukusabela kwamakhemikhali ngaphansi kwezimo ezithambile livula indlela yezixazululo eziqhubekayo, ezisebenzayo.
Kafushane, anataseI-TiO2iyinhlanganisela enezici eziningi ezinohlu olubanzi lwezinhlelo zokusebenza emikhakheni ehlukene. Izakhiwo zayo ze-photocatalytic, optical, electronic and antimicrobial ziyenza ibe yimpahla ebalulekile yemvelo, imboni, ukunakekelwa kwezempilo kanye nentuthuko yezobuchwepheshe. Njengoba ucwaningo nokuqamba okusha kuqhubeka kwenzeka, amandla e-anatase titanium dioxide kulindeleke ukuthi akhuthaze ukuthuthukiswa kwezinguquko futhi alolonge isimo sesayensi nezimboni.
Emzamweni oqhubekayo wokuhlola amandla ezinto zokwakha, i-anatase titanium dioxide isiphenduke isibani sezinto ezintsha, enikeza ingcebo yamathuba okubhekana nezinselele zomhlaba wonke futhi iqhubekisele phambili inqubekela phambili kwezesayensi nobuchwepheshe.
