Iyini i-photocatalysis yokukhanya ebonakalayo? Uyini umgomo we-photocatalysis yokukhanya ebonakalayo? Kungani kufanele usebenzise i-photocatalysis yokukhanya ebonakalayo?

Isimiso sokukhanya esibonakalayo esibonakalayo sisekelwe ekukhanyeni okukhanyayo kwe-irradiation light catalyst, i-catalyst valence band ye-light ground state electron transition to the conduction band, ukukhiqiza umgodi ozalwa ngokukhanya nokukhanya kwe-electronic, umgodi okhanyayo nama-molecule wamanzi ukuze ukhiqize ama-radicals mahhala e-hydroxyl, ama-electron kanye Ukusabela kwe-oxygen molecule kukhiqiza i-super oxygen anion, kanye nezimbobo, i-hydroxyl radicals kanye nokukhiqizwa kwe-superoxide anion, izinhlobo ze-oksijini ezisebenzayo zingehlisa ama-molecule ephunga, izinto eziphilayo, amabhaktheriya nezinye izinto ezingcolisayo zibe amanzi ne-carbon dioxide namanye ama-molecule amancane. Inani elincane le-N, S no-P ku-organic matter lizokhiqiza i-nitrate, i-sulfate, i-phosphate nokunye ngemva kokuwohloka, ukuze kudlale umphumela wokuqeda ubuthi, ukuqeda iphunga kanye nomphumela wokuvala inzalo. Ubuchwepheshe bokugqoka obukhanyayo obubonakalayo be-photocatalytic buhlinzeka ngesixazululo esisha esiluhlaza sokwelashwa kwendawo yomoya yangaphakathi nangaphandle.
