I-Titanium dioxide iyi-titanium oxide eyenzeka ngokwemvelo esithole ukunakwa okusabalele ngenxa yobubanzi bayo bezicelo ezimbonini ezahlukahlukene. Kusukela esikrinini selanga kuya kupende, umbala wokudla kuya ku-photocatalyst, i-titanium dioxide iyinhlanganisela eguquguqukayo ekweleta izakhiwo zayo ngesakhiwo sayo esiyingqayizivele. Kule bhulogi, sizobheka kabanziukwakheka kwe-titanium dioxidefuthi uhlole ukuthi isiza kanjani ukusetshenziswa kwayo okuningi.
Enhliziyweni yokuguquguquka kwe-titanium dioxide kunesakhiwo sayo sekristalu. I-Titanium dioxide ikhona ngezindlela ezintathu eziyinhloko zekristalu: i-rutile, i-anatase, ne-brookite. Kulezi, i-rutile ne-anatase yizindlela ezivame kakhulu, ngayinye inokuhlelwa kwayo okuhlukile kwe-athomu.
I-Rutile iyindlela ezinzile futhi echichimayotitanium dioxidefuthi ibonakala ngesakhiwo sayo se-lattice esiminyene. Ukuhlelwa kwe-titanium nama-athomu omoya-mpilo ku-rutile kubangela inkomba yayo ephezulu ye-refractive, okuyenza ibe isihlungi se-UV esifanelekile se-pigments, i-coatings ngisho ne-sunscreen. Isakhiwo sika-Rutile esisondelene kakhulu sinomthelela ekuzinzeni kwayo okuphezulu kwamakhemikhali, okuyenza ifanelekele ukufakwa kwezinto ezikwazi ukumelana nokugqwala.
U-Anatase, ngakolunye uhlangothi, unesakhiwo esivulekile futhi esiminyene kancane futhi ubonisa izakhiwo ezihlukile uma kuqhathaniswa ne-rutile. Yaziwa ngomsebenzi wayo okhethekile we-photocatalytic, i-anatase ithole izinhlelo zokusebenza ezindaweni ezifana nokulungiswa kwemvelo, izindawo ezizihlanzayo, kanye nokukhiqizwa kwe-hydrogen ngokuhlukana kwamanzi. Ukuhlelwa kwe-athomu okuyingqayizivele ku-anatase kunika amandla ukukhiqizwa okuphumelelayo kwamapheya e-electron-hole lapho kuvezwe ekukhanyeni, okukunikeza amandla e-photocatalytic.
Ikhono le-Titanium dioxide lokuba khona ezinhlobonhlobo ze-nanostructures lithuthukisa futhi ukuguquguquka kwayo. I-Nanoscale titanium dioxide inendawo ephezulu kuya kuvolumu yesilinganiso futhi ibonisa ukusebenza kabusha okuthuthukisiwe kanye nezakhiwo zokusabalalisa ukukhanya, okuyenza ibe yigugu ezinhlelweni ezifana ne-photovoltaics, izinzwa kanye nezingubo zokulwa namagciwane. Ikhono lokuhlanganisa i-titanium dioxide nanostructures livula izindlela ezintsha zokusetshenziswa kwayo kubuchwepheshe obuphambili.
Ukuqonda ukwakheka kwe-titanium dioxide kubalulekile ekwandiseni ukusebenza kwayo ezinhlelweni ezithile. Ngokulawula ifomu lekristalu, usayizi wezinhlayiyana kanye nezakhiwo ezingaphezulu, abacwaningi nonjiniyela bangakwazi ukushuna kahleizakhiwo ze-titanium dioxideukuhlangabezana nezidingo zezimboni ezahlukene. Kungakhathaliseki ukuthi isebenzisa amandla ayo okuvimbela i-UV ekwakhiweni kwesikrini selanga noma ukusebenzisa umsebenzi wayo we-photocatalytic ukuze kulungiswe imvelo, ukwakheka kwe-titanium dioxide kuwuhlaka lokusebenza kwayo ngezindlela eziningi.
Kafushane, ukwakheka kwe-titanium dioxide, okuhlanganisa uhlobo lwayo oluyikristalu kanye ne-nanostructure, isekela ukuguquguquka kwayo okumangalisayo kanye nokusetshenziswa kwayo ezimbonini ezihlukahlukene. Ngokwembula ukwakheka kwayo okuyinkimbinkimbi, ososayensi nabasunguli bayaqhubeka nokuvula amandla aphelele e-titanium dioxide, bevula indlela yokusetshenziswa kwenoveli nezixazululo ezisimeme. Njengoba sijula ebudlelwaneni besakhiwo nesakhiwo se-titanium dioxide, singalindela ukubona inqubekelaphambili eyengeziwe ekusebenziseni izici zayo eziyingqayizivele ukuze kuzuze umphakathi nendawo ezungezile.
