Njengoko imeko-bume iya isiba mandundu, abantu banikela ingqalelo ngakumbi nangakumbi ekukhuselweni kwendalo.Ezinye iindlela zokucocwa kwamanzi amdaka emveli kunzima ukuhlangabezana neemfuno zophuhliso ngenxa yeemveliso ezininzi, unyango oluntsonkothileyo lwasemva konyango, ungcoliseko lwesibini kunye nezinye izithintelo.Itekhnoloji ye-Photocatalytic oxidation ifumene ingqwalasela eyongeziweyo kwiingenelo zayo ezibalaseleyo ezifana nokusetyenziswa kwamandla aphantsi, iimeko zokusabela okuthambileyo, ukusebenza okulula, kwaye akukho ngcoliseko lwesibini. 

I-photocatalysis ye-semiconductor ithetha ukuba i-semiconductor catalyst ivelisa izibini ze-electron-hole phantsi kwesenzo sokukhanya okubonakalayo okanye ukukhanya kwe-ultraviolet.I-O₂, H₂I-O kunye neemolekyuli ezingcolisa i-adsorbed kumphezulu we-semiconductor zamkela ii-electron ezenziwe ngefoto okanye imingxunya, kwaye uthotho lweempendulo ze-redox zenzeka.Yindlela yokuthatha imichiza yokuthoba ungcoliseko oluyityhefu lube zizinto ezingeyotyhefu okanye ezingenatyhefu.Le ndlela inokuthi iqhutywe kwiqondo lokushisa, inokusebenzisa ukukhanya kwelanga, inoluhlu olubanzi lwemithombo ye-catalyst, ayibizi, ayinayo ityhefu, izinzileyo, kunye nokusetyenziswa kwakhona, akukho ukungcola okwesibini kunye nezinye iingenelo.Okwangoku, uninzi lweefotocatalysts ezonakalise ungcoliseko lwendalo zizinto ze-N-type semiconductor, njengeTiO.₂, ZnO, CdS, WO, SnO₂, Fe₂O₃, njl.

Kwiminyaka yakutshanje, njengendlela esebenzayo, iteknoloji ye-photocatalytic inesiphumo esihle sonyango kwizinto ezingcolisayo.Phakathi kwazo, i-semiconductor heterogeneous photocatalysis iye yaba yeyona itekhnoloji entsha itsala amehlo kuba inokwenza ngokupheleleyo kwaye yonakalise izinto ezahlukeneyo eziphilayo kunye ne-inorganic kumoya ongcolileyo kunye namanzi amdaka.Le teknoloji inokuthoba ngokupheleleyo izinto ezingcolisa izinto eziphilayo zibe yi-CO₂, H₂O, C1-, P043- kunye nezinye izinto ezingaphiliyo, ukunciphisa kakhulu umxholo we-organic (TOC) wenkqubo;ezininzi ezingcolisa inorganic ezifana CN-, NOx, NH₃, H₂S, njl.

Phakathi kwee-photocatalysts ezininzi ze-semiconductor, i-titanium dioxide kunye ne-nano cuprous oxide bezisoloko zingundoqo wophando lwe-photocatalysis ngenxa yobuchule babo be-oxidizing, umsebenzi ophezulu we-catalytic, kunye nokuzinza okulungileyo.Iingcali ezininzi zikholelwa ukuba uCu₂I-O inamathuba amahle okusebenza kwi-photocatalytic degradation ye-organic pollutants, kwaye kulindeleke ukuba ibe sisizukulwana esitsha se-semiconductor photocatalysts emva kwe-titanium dioxide.Cu₂I-O nano ineepropathi zekhemikhali ezizinzileyo kunye nekhono elinamandla le-oxidizing phantsi kokukhanya kwelanga, okunokuthi ekugqibeleni kufake i-oxidize ungcoliseko lwendalo emanzini ukuvelisa iCO.₂kunye noH₂O. Ngoko ke, nano Cu₂I-O ifaneleke ngakumbi kunyango oluphezulu lwamanzi amdaka ahlukeneyo edayi.Abaphandi baye basebenzisa i-nano Cu₂O ukuthotywa kwe-photocatalytic ye-methylene blue, njl., kwaye iphumelele iziphumo ezilungileyo. 

Kule minyaka yangoku,cuprous oxide nanoparticleszisetyenziswe ngokubanzi kunyango lwamanzi amdaka kunye nobuchwepheshe bokucoca.Xa kuthelekiswa nobunye ubugcisa bokucocwa kwamanzi esintu, banezibonelelo zokusebenza ngokupheleleyo, ixabiso eliphantsi, uzinzo kunye nokusetyenziswa kokukhanya kwelanga, kwaye banethemba elihle nelibanzi.TiO₂ngokuqhelekileyo isetyenziselwa ukunyanga ilindle ngokukhanya kwelanga.Nangona kunjalo, le nto idinga ukusebenza kwe-ultraviolet kwaye inemiqobo emininzi.Ke ngoko, ukukhanya okubonakalayo njengomthombo wamandla okukhanya wokucoca ugutyulo bekusoloko kuyinjongo elandelwa zizazinzulu.

I-Guangzhou Hongwu Material Technology Co., Ltd. inonikezelo lwexesha elide oluzinzileyo lwe-cuprous oxide (Cu2O) nanoparticles kwiibhetshi ezithengiswa ngokuthe ngqo kwifektri, ukuqinisekiswa komgangatho, kunye nexabiso elifanelekileyo.UHongwu Nano ulindele ukusebenzisana nawe.
