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 electron transition to the conduction band, ikhiqiza ukukhanya okuzalwa imbobo nokukhanya kwe-electronic, imbobo ekhanyayo nama-molecule amanzi ukukhiqiza ama-radicals mahhala we-hydroxyl, ama-electron kanye ne-oksijini ye-molecule yokusabela ikhiqiza i-super oxygen anion, kanye nemigodi yokukhiqiza i-oksijini ye-superoxide, i-hydroxyl yokukhiqiza i-radical hydroxygen, i-hydroxyl ne-radical hydroxyl. ama-molecule ephunga, izinto eziphilayo, amabhaktheriya nezinye izinto ezingcolisayo zibe emanzini kanye 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.
