Anatase nano titanium dioxide / TiO2 nanoparticles yog cov hmoov dawb dawb nrog cov khoom me me thiab cov khoom zoo photocatalytic.Nws tus nqi photocatalytic yog ntau dua li ntawm cov titanium dioxide zoo tib yam, thiab nws tau siv dav hauv ntau yam kev lag luam catalytic.

Nano-titanium dioxide muaj cov tshuaj zoo thiab thermal stability, muaj kev nyab xeeb thiab tsis muaj tshuaj lom, thiab nws cov yam ntxwv tseem ceeb thiab kev siv yog raws li hauv qab no:

1. Nano titanium dioxide tsis muaj tshuaj lom thiab tsis muaj mob, thiab muaj kev sib raug zoo nrog lwm cov ntaub ntawv raw.
2. Haum rau photocatalyst coatings, diatomaceous earth coatings, self-cleaning coatings, self-cleaning ceramic pigments, etc. Photocatalyst-qib nano-titanium dioxide: Nano-sized hmoov ua los ntawm nano-TiO2 doped nrog tej yam hlau los yog hlau oxides yuav ua tau. siv los tsim photocatalytic catalysts (hom anatase).Thaum cov hmoov yog irradiated nrog lub teeb tsawg dua 400nm, lub valence band electrons raug xa mus rau lub conduction band, tsim electrons thiab qhov thiab interacting nrog O2 thiab H2O adsorbed rau saum npoo los tsim superoxide anion radicals, uas muaj lub teeb Catalytic decomposition ntawm teeb meem. gases, organic pollutants thiab photocatalytic antibacterial functions, tuaj yeem siv dav hauv huab cua purification thiab dej phwj kho thiab lwm yam.

3. Nws muaj cov nyhuv photocatalytic zoo, tuaj yeem decompose cov pa phem thiab qee cov tshuaj inorganic hauv huab cua, thiab inhibit qhov kev loj hlob ntawm cov kab mob thiab cov kev ua ntawm cov kab mob, thiaj li ua tiav huab cua purification, sterilization, deodorization thiab mildew tiv thaiv.Nano-titanium dioxide muaj cov kab mob tua kab mob, kev ntxuav tus kheej, thiab tuaj yeem txhim kho cov khoom adhesion zoo.

4. Anatase nano titanium dioxide muaj cov khoom me me thiab cov cheeb tsam loj.Nano titanium dioxide muaj kev ua haujlwm siab, muaj zog tiv thaiv kab mob, thiab cov khoom yog yooj yim tawg.Kev sim tau pom tias nano-titanium dioxide muaj peev xwm tiv thaiv kab mob Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Salmonella thiab Aspergillus.Nws tau siv dav hauv cov khoom siv tshuaj tua kab mob hauv cov teb ntawm textiles, ceramics, roj hmab, thiab lwm yam, thiab tau siv dav thiab txais tos los ntawm cov neeg siv khoom.
