He aha ka photocatalysis māmā? He aha ke kumu o ka photocatalysis māmā? No ke aha e hoʻohana ai i ka photocatalysis māmā?

Hoʻokumu ʻia ka loina catalytic māmā ʻike ʻia ma luna o ka ikehu kukui irradiation māmā catalyst, catalyst valence band o ka māmā ʻāina mokuʻāina electron hoʻololi i ka conduction band, hana i ka malamalama hānau puka a me ka uila uila, puka māmā me nā mole wai e hoʻohua i nā radical manuahi hydroxyl, electrons a ʻO ka hopena mole oxygen e hoʻopuka i ka anion oxygen super, a me nā lua, nā radical hydroxyl a me ka hana anion superoxide, hiki i nā ʻano oxygen Reactive ke hoʻohaʻahaʻa i nā molekala ʻala, nā mea kūlohelohe, bacteria a me nā mea haumia ʻē aʻe i loko o ka wai a me ka carbon dioxide a me nā mea liʻiliʻi liʻiliʻi. ʻO kahi liʻiliʻi o N, S a me P i loko o ka mea organik e hoʻohua i ka nitrate, sulfate, phosphate a pēlā aku ma hope o ka degradation, i mea e pāʻani ai i kahi detoxification, deodorization a me ka hopena sterilization. Hāʻawi ka ʻenehana uhi photocatalytic māmā i kahi ʻōmaʻomaʻo hou no ka mālama ʻana i ka ea o loko a me waho.
