ʻO Anatase nano titanium dioxide / TiO2 nanoparticles he pauka pauka keʻokeʻo me ka liʻiliʻi liʻiliʻi a me nā waiwai photocatalytic maikaʻi.ʻOi aku ka kiʻekiʻe o kāna photocatalytic rate ma mua o ka titanium dioxide maʻamau, a hoʻohana nui ʻia i nā ʻano catalytic ʻoihana.

ʻO ka Nano-titanium dioxide ka maikaʻi kemika a me ka thermal stability, palekana a ʻaʻohe mea ʻawaʻawa, a ʻo kāna mau hiʻohiʻona nui a me nā noi penei:

1. ʻO ka Nano titanium dioxide he meaʻawaʻawaʻole a maikaʻiʻole, a he kūpono maikaʻi me nā mea'ē aʻe.
2. He kūpono no nā uhi kiʻi kiʻi, nā uhi honua diatomaceous, nā uhi hoʻomaʻemaʻe ponoʻī, hoʻomaʻemaʻe ponoʻī i nā puaʻa seramika, a me nā mea ʻē aʻe. hoʻohana ʻia e hana i nā catalysts photocatalytic (ʻano anatase).Ke hoʻomālamalama ʻia ka pauka me ka māmā o lalo o 400nm, ua hoʻouna ʻia nā electrons valence band i ka conduction band, e hana ana i nā electrons a me nā lua a me ka launa pū ʻana me O2 a me H2O adsorbed ma ka ʻili e hoʻohua i nā radical anion superoxide, nona ka māmā Catalytic decomposition o ka pōʻino. nā kinoea, nā mea haumia kūlohelohe a me nā hana antibacterial photocatalytic, hiki ke hoʻohana nui ʻia i ka hoʻomaʻemaʻe ʻana i ka ea a me ka mālama ʻana i ka wai a me nā māla ʻē aʻe.

3. He hopena photocatalytic maikaʻi, hiki ke hoʻoheheʻe i nā kinoea ʻino a me kekahi mau pūhui inorganic i ka lewa, a keʻakeʻa i ka ulu ʻana o ka bacteria a me ka hana o nā maʻi virus, i mea e hoʻokō ai i ka hoʻomaʻemaʻe ʻana i ka ea, sterilization, deodorization a me ka pale ʻana i ka mildew.Loaʻa i ka Nano-titanium dioxide nā antibacterial, nā hopena hoʻomaʻemaʻe ponoʻī, a hiki nō hoʻi ke hoʻomaikaʻi nui i ka pili ʻana o ka huahana.

4. Anatase nano titanium dioxide ua like ka nui o ka ili a me ka nui kiko'ī ili.Loaʻa i ka Nano titanium dioxide ka hana kiʻekiʻe o ka honua, ka ikaika antibacterial ikaika, a maʻalahi ka hoʻopuehu ʻana o ka huahana.Ua hōʻike ʻia nā hoʻokolohua he ikaika bactericidal ikaika ka nano-titanium dioxide e kūʻē iā Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Salmonella a me Aspergillus.Ua hoʻohana nui ʻia i nā huahana antibacterial ma nā ʻano textiles, ceramics, rubber, etc., a ua hoʻohana nui ʻia a hoʻokipa ʻia e nā mea hoʻohana.
