Yintoni ifotocatalysis yokukhanya ebonakalayo?Uthini umgaqo we-photocatalysis yokukhanya okubonakalayo?Kutheni usebenzisa ukukhanya okubonakalayo kwe-photocatalysis?

Umgaqo wokukhanya obonakalayo wokukhanya usekwe kukukhanya okukhanyayo okukhanyisa ukukhanya, i-catalyst valence band yokukhanya komhlaba i-electron inguqu kwi-conduction band, ukuvelisa umngxuma ozalwe ngokuzalwa kunye nokukhanya kwe-elektroniki, umngxuma okhanyayo kunye neemolekyuli zamanzi ukuvelisa i-hydroxyl free radicals, ii-electron kunye Ukusabela kwemolekyuli ye-oksijini ivelisa i-anion ye-oxygen ephezulu, kunye nemingxuma, i-hydroxyl radicals kunye ne-superoxide anion imveliso, iintlobo ze-oksijini ezisebenzayo zinokuthoba iimolekyuli zevumba, izinto eziphilayo, iibhaktheriya kunye nezinye izinto ezingcolisa amanzi kunye nekhabhon diokside kunye nezinye iimolekyuli ezincinci.Inani elincinci le-N, i-S kunye ne-P kwi-organic matter iya kuvelisa i-nitrate, i-sulfate, i-phosphate kunye nokunye emva kokuthotywa, ukuze kudlale i-detoxification, i-deodorization kunye ne-sterilization effect.Ubuchwephesha obubonakalayo bokugquma i-photocatalytic bubonelela ngesisombululo esitsha esiluhlaza sonyango lwangaphakathi nangaphandle lomoya.
