Ha tikoloho e ntse e senyeha, batho ba ela hloko haholoanyane ho sireletsa tikoloho.Mekhoa e meng ea setso ea ho hloekisa metsi a litšila e thata ho fihlela litlhoko tsa nts'etsopele ka lebaka la lihlahisoa tse ngata, phekolo e rarahaneng ka mor'a phekolo, tšilafalo ea bobeli le mefokolo e meng.Theknoloji ea Photocatalytic oxidation e amohetse tlhokomelo e ntseng e eketseha bakeng sa melemo ea eona e ikhethang joalo ka tšebeliso e tlase ea matla, maemo a karabelo e bonolo, ts'ebetso e bonolo, 'me ha ho na tšilafalo ea bobeli.
Semiconductor photocatalysis e bolela hore semiconductor catalyst e hlahisa lipara tsa electron-hole tlas'a ketso ea leseli le bonahalang kapa leseli la ultraviolet.The O2, H2O le limolek'hule tse silafetseng tse adsorbed holim'a semiconductor holim'a li-electrone kapa masoba a hlahisoang ke lifoto, 'me letoto la liketso tsa redox li etsahala.Ke mokhoa o joalo oa lik'hemik'hale oa ho theola litšila tse chefo hore e be lintho tse seng chefo kapa tse seng chefo.Mokhoa ona o ka etsoa ka mocheso oa kamore, o ka sebelisa khanya ea letsatsi, o na le mefuta e mengata ea mehloli ea li-catalyst, e theko e tlaase, ha e na chefo, e tsitsitse ebile e sebelisoa hape, ha ho na tšilafalo ea bobeli le melemo e meng.Hajoale, li-photocatalyst tse ngata tse nyenyefatsang litšila tsa tlhaho ke lisebelisoa tsa semiconductor tsa mofuta oa N, joalo ka TiO.2, ZnO, CdS, WO, SnO2, Fe2O3, joalo-joalo.
Lilemong tsa morao tjena, e le mokhoa o atlehang, theknoloji ea photocatalytic e na le phello e ntle ea phekolo ho litšila tsa tikoloho.Har'a tsona, semiconductor heterogeneous photocatalysis e fetohile theknoloji e ncha e hapang mahlo ka ho fetisisa hobane e ka senya le ho senya lintho tse fapa-fapaneng tse phelang le tse sa tloaelehang moeeng o silafetseng le metsi a litšila.Theknoloji ena e ka theola litšila tse ngata tsa manyolo ka botlalo ho CO2, H2O, C1-, P043- le lintho tse ling tsa inorganic, ho fokotsa haholo kakaretso ea organic content (TOC) ea sistimi;litšila tse ngata tse sa pheleng tse kang CN-, NOx, NH3, H2S, joalo-joalo e ka boela ea nyenyefatsoa ka liketso tsa photocatalytic.
Har'a li-photocatalysts tse ngata tsa semiconductor, titanium dioxide le nano cuprous oxide esale e le setsi sa lipatlisiso tsa photocatalysis ka lebaka la matla a tsona a matla a oxidizing, ts'ebetso e phahameng ea catalytic, le botsitso bo botle.Litsebi tse ngata li lumela hore Cu2O na le litebello tse ntle tsa ts'ebeliso ts'ebetsong ea photocatalytic ea litšila tse phelang, 'me e lebelletsoe ho fetoha moloko o mocha oa li-semiconductor photocatalysts kamora titanium dioxide.Cu2O nano e na le lik'hemik'hale tse tsitsitseng tse batlang li tsitsitse le bokhoni bo matla ba oxidizing tlas'a ts'ebetso ea khanya ea letsatsi, e ka qetellang e ka oxidize ka ho feletseng litšila tse phelang metsing ho hlahisa CO.2le H2O. Ka hona, nano Cu2O e loketse haholoanyane kalafo e tsoetseng pele ea metsi a litšila a dae.Bafuputsi ba sebelisitse nano Cu2O ho senyeha ha photocatalytic ea methylene blue, joalo-joalo, 'me e fumane liphello tse ntle.
