Mugihe ibidukikije byangiritse, abantu barushaho kwita kubidukikije.Bumwe mu buryo bwa gakondo bwo gutunganya amazi mabi biragoye guhaza ibikenewe byiterambere kubera ibicuruzwa byinshi biva mu mahanga, bigoye nyuma yo kuvurwa, umwanda wa kabiri nizindi mbogamizi.Tekinoroji ya okiside ya Photocatalytic yitabiriwe cyane ninyungu zayo zidasanzwe nko gukoresha ingufu nke, imiterere yoroheje, imikorere yoroshye, kandi nta mwanda wa kabiri. 

Semiconductor Photocatalyse isobanura ko catisitori ya semiconductor itanga electron-umwobo byombi munsi yumucyo ugaragara cyangwa urumuri ultraviolet.O.₂, H.₂O na molekile ihumanya yamamajwe hejuru ya semiconductor yemera amafoto yakozwe na electron cyangwa umwobo, kandi urukurikirane rwa redox rubaho.Nuburyo bwo gufotora kugirango bugabanye imyanda ihumanya mubintu bidafite uburozi cyangwa uburozi buke.Ubu buryo burashobora gukorwa mubushyuhe bwicyumba, bushobora gukoresha urumuri rwizuba, bukagira amasoko menshi ya catalizator, ntibihendutse, bidafite uburozi, butajegajega, kandi bushobora gukoreshwa, nta mwanda wongeyeho nibindi byiza.Kugeza ubu, amafoto menshi yangiza imyanda ihumanya ni ibikoresho byo mu bwoko bwa N-semiconductor, nka TiO₂, ZnO, CdS, WO, SnO₂, Fe₂O₃, n'ibindi.

Mu myaka yashize, nkuburyo bwiza, tekinoroji ya fotokatike igira ingaruka nziza yo kuvura ibidukikije.Muri byo, semiconductor heterogeneous Photocatalyse yahindutse ikoranabuhanga rishya rishimishije cyane kuko rishobora guhagarika rwose no kwangiza ibintu bitandukanye kama n’ibinyabuzima mu kirere cyanduye n’amazi yanduye.Iri koranabuhanga rirashobora kwangiza rwose imyanda ihumanya muri CO₂, H.₂O, C1-, P043- nibindi bintu bidafite umubiri, kugirango ugabanye cyane ibinyabuzima byose (TOC) bya sisitemu;imyanda myinshi ihumanya nka CN-, NOx, NH₃, H.₂S, nibindi birashobora kandi guteshwa agaciro binyuze mumafoto ya fotokatike.

Muri fotokateri nyinshi ya semiconductor, dioxyde de titanium na nano cuprous oxyde yamye yibanze kumurongo wubushakashatsi bwa Photocatalysis kubera ubushobozi bukomeye bwa okiside, ibikorwa bya catalitike, hamwe no guhagarara neza.Abahanga benshi bemeza ko Cu₂O ifite ibyifuzo byiza byo kwangirika kwifotora yangiza imyanda ihumanya, kandi biteganijwe ko izahinduka igisekuru gishya cyamafoto ya semiconductor nyuma ya dioxyde de titanium.Cu₂O nano ifite imiterere ihamye ya chimique hamwe nubushobozi bukomeye bwa okiside ikoresheje urumuri rwizuba, amaherezo ishobora guhumeka rwose imyanda ihumanya mumazi kugirango itange CO₂na H.₂O. Kubwibyo, nano Cu₂O irakwiriye cyane gutunganya amazi mabi atandukanye.Abashakashatsi bakoresheje nano Cu₂O fotokatalitike yangirika ya methylene ubururu, nibindi, kandi byageze kubisubizo byiza. 

Mu myaka yashize,cuprous oxide nanoparticleszagiye zikoreshwa cyane mu gutunganya amazi mabi no gutunganya.Ugereranije nubundi buryo bwa tekinoroji yo gutunganya amazi, bafite ibyiza byo gukora neza cyane, igiciro gito, ituze no gukoresha urumuri rwizuba, kandi bafite ibyerekezo byiza kandi binini.TiO₂isanzwe ikoreshwa mu gutunganya umwanda ukoresheje izuba.Nyamara, iyi ngingo isaba gukora ultraviolet kandi ifite ibibi byinshi.Kubwibyo, urumuri rugaragara nkisoko yumucyo wo gutunganya imyanda yamye nintego yakurikiranwe nabahanga.

Guangzhou Hongwu Material Technology Co., Ltd. ifite isoko ryigihe kirekire ryogutanga ibikombe bya oxyde (Cu2O) nanoparticles mubice hamwe kugurisha ibicuruzwa bitaziguye, ubwishingizi bufite ireme, nigiciro cyiza.Hongwu Nano yiteze gufatanya nawe.
