Titanium dioxide anatase nano ọkwa TiO2

Ngwaof:

1. Nano titanium dioxide anatase nwere ọrụ antibacterial site na fotocatalytic Njirimara nke nwere ike ibibi nje bacteria ma ọ bụ gbochie mmepụta ha.TiO2 nwekwara ọrụ nke melite n'ibu Njirimara site urughuru dispersion ike.2. Ụfọdụ n'ime fotocatalytic Njirimara nke nanomaterials nwere ike ịmepụta na nanometer photocatalytic mkpuchi.N'ime nnwale anyị, anyị na-eji HWNANO TiO2 titanium dioxide anatase mgbe ọgwụgwọ elu pụrụ iche, nke jikọtara ya na mkpuchi resin acrylic dị ọcha, na nnwale unit dị mkpa gosiri na ọ nwere mbibi catalytic doro anya na nitrogen oxides, griiz na formaldehyde.N'ihi na nitrogen oxide mbelata arụmọrụ nwere ike iru 80%.3. Titanium dioxide nwere atọ dị iche iche crystal usoro Ọdịdị: Anatase ụdị (Anatase), Brookite na Rutile ụdị (Rutile).Anatase titanium dioxide nwere elu photocatalytic ọxịdashọn ikike, ya machibidoro iwu obosara maka Eg = 3.2 eV, Ẹkot a wavelength nke 387 NRN ìhè ike, ọ bụ naanị na ultraviolet mpaghara, ya mere na TiO2 photocatalytic ọxịdashọn mmeghachi omume kwesịrị uv ìhè isi iyi, dị otú ahụ. dị ka ìhè anyanwụ, halogen tungsten dean, ìhè oriọna mercury.N'okpuru ọkụ ultraviolet, eriri valence ya na eletrọn na-ebunye na band conduction, na valence band na-emepụta oghere.Usoro bụ na n'okpuru uv irradiation, TiO2 na-emepụta a free electron, Ha na-eme ka ikuku oxygen na ikuku rụọ ọrụ na-emepụta oxygen na-arụ ọrụ na free radicals.4. Reactive oxygen umu na OH radicals nwere elu reactivity, mgbe pollutants adsorption n'elu, ọ ga-ejikọta na free electrons na The mepụta redox reaction.So dị ka iji nweta ebumnuche nke iwepu mmetọ.Maka ozi ndị ọzọ nke nano TiO2 ntụ ntụ, biko kpọtụrụ anyị n'efu.
