I-Titanium dioxide yi-titanium oxide eyenzeka ngokwemvelo efumene ingqalelo ebanzi ngenxa yoluhlu olubanzi lwezicelo kumashishini ahlukeneyo. Ukusuka kwi-sunscreen ukuya kwipeyinti, umbala wokutya ukuya kwi-photocatalyst, i-titanium dioxide yikhompawundi eguquguqukayo etyala iipropati zayo kwisakhiwo sayo esisodwa. Kule bhlog, siza kujonga ngakumbiubume be-titanium dioxidekwaye ujonge ukuba iququzelela njani ukusetyenziswa kwayo okuninzi.
Embindini wokuguquguquka kwe-titanium dioxide kukho ubume bayo bekristale. I-Titanium dioxide ikhona kwiintlobo ezintathu eziphambili zekristale: i-rutile, i-anatase, kunye ne-brookite. Kwezi, i-rutile kunye ne-anatase zezona fom zixhaphakileyo, nganye inelungiselelo layo elilodwa leathom.
I-Rutile yeyona ndlela izinzile kwaye ininzititanium dioxidekwaye ibonakaliswe ngesakhiwo sayo esixineneyo selathisi. Ukulungelelaniswa kwe-titanium kunye neeathom ze-oxygen kwi-rutile kukhokelela kwisalathiso saso esiphezulu se-refractive, esenza ukuba ibe sisihluzo esifanelekileyo se-UV kwi-pigments, iingubo kunye ne-sunscreen. Ulwakhiwo olusondeleleneyo lwe-Rutile lukwanegalelo ekuzinzeni kwayo okuphezulu kweekhemikhali, oko kuyenza ifaneleke kwizicelo zemathiriyeli ezinganyangekiyo.
U-Anatase, kwelinye icala, unesakhiwo esivulekileyo nesincinci kwaye ubonisa iipropati ezahlukeneyo xa kuthelekiswa ne-rutile. Eyaziwayo ngomsebenzi wayo okhethekileyo we-photocatalytic, i-anatase ifumene izicelo kwiindawo ezifana nokulungiswa kwendalo, iindawo zokuzicoca, kunye nokuveliswa kwe-hydrogen ngokuhlukana kwamanzi. Ulungelelwaniso olulodwa lweathom kwi-anatase luvumela ukuveliswa okusebenzayo kwee-electron-hole pairs xa ibonakaliswe ekukhanyeni, inika amandla e-photocatalytic.
Ukukwazi kwe-Titanium dioxide ukubakho kwiindidi ze-nanostructures kwandisa ngakumbi ukuguquguquka kwayo. I-Nanoscale titanium dioxide inommandla ophakamileyo ophezulu ukuya kumlinganiselo wevolumu kwaye ibonisa ukusebenza okuphuculweyo kunye neempawu zokusabalalisa ukukhanya, okwenza kube luncedo kwizicelo ezifana ne-photovoltaics, i-sensor kunye ne-antimicrobial coatings. Ukukwazi ukulungelelanisa i-titanium dioxide nanostructures ivula iindlela ezintsha zokusetyenziswa kwayo kwiiteknoloji eziphambili.
Ukuqonda ubume be-titanium dioxide kubalulekile ekuphuculeni ukusebenza kwayo kwizicelo ezithile. Ngokulawula ifom yekristale, ubungakanani besuntswana kunye neempawu ezingaphezulu, abaphandi kunye neenjineli banokucombulula kakuhleiimpawu ze-titanium dioxideukuhlangabezana neemfuno zamashishini ahlukeneyo. Nokuba ikhulisa amandla ayo okuthintela i-UV ekubunjweni kwe-sunscreen okanye ukusebenzisa ifotocatalytic yokulungiswa kokusingqongileyo, ulwakhiwo lwe-titanium dioxide luyilo lokuguquguquka kwayo.
Isishwankathelo, isakhiwo se-titanium dioxide, kubandakanywa nefom ye-crystalline kunye ne-nanostructure, isekela ukuguquguquka kwayo okuphawulekayo kunye nokusetyenziswa kwiindidi ezahlukeneyo zamashishini. Ngokutyhila ubume bayo obuntsonkothileyo, izazinzulu kunye nabavelisi bayaqhubeka nokuvula amandla apheleleyo e-titanium dioxide, bevula indlela yezicelo ezintsha kunye nezisombululo ezizinzileyo. Njengoko singena nzulu kubudlelwane besakhiwo-indawo ye-titanium dioxide, sinokulindela ukubona inkqubela phambili ekusebenziseni iimpawu zayo ezizodwa ukuze kuxhamle uluntu kunye nokusingqongileyo.
