Yintoni i-photocatalysis yokukhanya okubonakalayo? Yintoni umgaqo we-photocatalysis yokukhanya okubonakalayo? Kutheni kufuneka usebenzise i-photocatalysis yokukhanya okubonakalayo?

Umgaqo wokukhanyisa obonakalayo usekelwe kwi-catalyst yokukhanya okubonakalayo, i-catalyst valence band yokukhanya komhlaba, utshintsho lwe-electron ukuya kwi-conduction band, ukuvelisa umngxuma wokuzalwa okhanyayo kunye ne-elektroniki yokukhanya, umngxuma wokukhanya kunye neemolekyuli zamanzi ukuvelisa ii-radicals zasimahla ze-hydroxyl, ii-electron kunye ne-molecule ye-oxygen zivelisa i-anion ye-super oxygen, kunye neembobo, ii-radicals ze-hydroxyl kunye nemveliso ye-anion ye-superoxide. Iintlobo ze-oxygen ezisebenzayo zingonakalisa iimolekyuli zevumba, izinto eziphilayo, iibhaktheriya kunye nezinye izinto ezingcolisayo emanzini kunye ne-carbon dioxide kunye nezinye iimolekyuli ezincinci. Inani elincinci le-N, i-S kunye ne-P kwizinto eziphilayo liya kuvelisa i-nitrate, i-sulfate, i-phosphate njalo njalo emva kokubola, ukuze idlale i-detoxification, i-deodorization kunye ne-sterilization effect. Itekhnoloji yokugquma ye-photocatalytic yokukhanya ebonakalayo ibonelela ngesisombululo esitsha esiluhlaza sonyango lwendawo yomoya yangaphakathi nangaphandle.
