Kuyini i-photocatalysis yokukhanya okubonakalayo? Uyini umgomo we-photocatalysis yokukhanya okubonakalayo? Kungani kufanele usebenzise i-photocatalysis yokukhanya okubonakalayo?

Isimiso sokukhanyisa esibonakalayo sisekelwe ekukhanyeni okubonakalayo, i-catalyst valence band yokukhanya komhlabathi, ukushintshela kwe-electron kuya ebhendini lokuhambisa, ukukhiqiza imbobo yokuzalwa ekhanyayo kanye ne-electronic ekhanyayo, imbobo ekhanyayo enama-molecule amanzi ukukhiqiza ama-radicals wamahhala e-hydroxyl, ama-electron kanye nokusabela kwe-molecule ye-oxygen kukhiqiza i-anion ye-super oxygen, kanye nezimbobo, ama-radicals e-hydroxyl kanye nokukhiqizwa kwe-anion ye-superoxide, Izinhlobo ze-oxygen ezisebenzayo zingalimaza ama-molecule ephunga, izinto eziphilayo, amabhaktheriya kanye nezinye izinto ezingcolisayo zibe ngamanzi kanye ne-carbon dioxide kanye namanye ama-molecule amancane. Inani elincane le-N, S kanye ne-P ezintweni eziphilayo lizokhiqiza i-nitrate, i-sulfate, i-phosphate njalo njalo ngemva kokubola, ukuze kudlale umphumela wokukhipha ubuthi emzimbeni, ukususa iphunga kanye nokubulala amagciwane. Ubuchwepheshe bokumboza ukukhanya okubonakalayo buhlinzeka ngesisombululo esisha esiluhlaza sokwelashwa kwendawo yomoya yangaphakathi nangaphandle.
