Suma:
Mumunda wemajeri emidziyo,titanium dioxide. Iyi denderedzwa ine zvivakwa zvakanaka zvemakemikari uye zvemuviri, zvichiita kuti zvive zvakakosha mumatunhu akati wandei. Kuti vanzwisise zvizere hunhu hwayo hwakasarudzika, titanium dioxide's Fascinting chimiro chinofanira kufunda zvakadzama. Mune ino blog post, isu tichaongorora chimiro cheTitanium dioxide uye akajekesa zvikonzero zvakakosha kumashure kwavo kwakakosha.
1. Crystal chimiro:
Titanium Dioxide ine chimiro chekristaro, chakatemwa zvakanyanya negadziriro yayo yakasarudzika yemaatomu. NyangweTio2ine matatu crystalline zvikamu (anatase, rusiri, ne brookite), isu tichatarisa pamhando mbiri dzinowanzoitika: rutily uye anatase.
A. Rutieti chimiro:
Chikamu cheRutile chinozivikanwa nekuda kweiyo tetragonal Cryarstal chimiro, mune imwe tomanium atom yakakomberedzwa nematanho matanhatu eokisijeni, kugadzira octahedron. Iyi gadziriro inoumba dense atomic denderedzwa ine gadziriro yepedyo gadziriso. Chimiro ichi chinopa ruzha rwekusarongeka uye kujaira, zvichiita kuti zviite zvakasiyana-siyana zvekushandisa, kusanganisira pendi, ceramics, uye kunyangwe sunscreen.
B. Anatase chimiro:
Panyaya yeAnatase, maatomu etambo anosungwa maatomu mashanu eokisijeni, achiumba octahedrons anogovana mipheto. Naizvozvo, urongwa uhwu hunoguma nechimiro chakavhurika chine maatomu mashoma pane nhamba yeyunivhesiti ichienzaniswa neRutile. Pasinei neyakaderera density, anatase inoratidzira yakanakisa Photocataly procataly
2. Energy band Gap:
Iyo Energy Band Gap imwe yakakosha hunhu hwe tii2 uye zvinobatsira kune izvo zvakasarudzika zvivakwa. Iyi gomba inosarudza magetsi emashoko ezvemashoko uye mafungiro ayo ekunyatsojekesa.
A. RUTICIL BAND YEMADZIMAI:
Rutile tio2ine bhendi rakamanikana rebhandi rinenge 3.0 ev, uchiita kuti iite mashoma magetsi conductor. Nekudaro, bhendi bhendi racho rinogona kutora Ultraviolet (UV) Chiedza, ichiita kuti ive yakakodzera kushandiswa muUV yeUV yeUV yakadai seSunscreen.
B. Anatase Band Chimiro:
Anatase, kune rumwe rutivi, inoratidza kuti band band webhandi rinenge 3.2 Ev. Hunhu uhwu hunopisira natase tio2 yakanaka kwazvo Photocataly basa. Paunenge uchivhenekwa nechiedza, elekitoni dziri muValence Band inofara uye kusvetukira muiri bhendi, zvichikonzera dzakasiyana siyana oxidation uye kuderedza maitiro kuti zviitike. Izvi zvivakwa zvakavhura musuwo kune ma application yakadai sekunatswa kwemvura uye mweya wekusvibisa mweya.
3. Kuremara uye kushandurwa:
The thechimiro che tii2haisi isina zvikanganiso. Izvi zvinokanganiswa uye kushandurwa kwakakosha kukanganisa zvivakwa zvavo zvemuviri uye zvemakemikari.
A. Oxygen Vachadenga:
Kuremara muchimiro cheokisijeni.
B. SOURT SEITIFICATION:
Kudzoserwa mashandiro ekugadzirisa, sekushandura neimwe shanduko yesimbi ions Semuenzaniso, kugadzirisa nesimbi yakadai sePlatin inogona kuvandudza kuita kwayo kweChinorita, nepo mapoka anoshanda esangano anogona kukurudzira kugadzikana kwezvinhu uye kufungidzira.
Mukupedzisa:
Kunzwisisa chimiro chinoshamisa cheTio2 chakashamisika kuti unzwisise zvimiro zvinoshamisa uye zvinoshandiswa zvakasiyana. Imwe neimwe crystalline fomu yeTio2 ine yakasarudzika zvivakwa, kubva kune yeTetragonal Rutile chimiro kune yakavhurika, PhotocatalyTical Active AnatasE Phase. Nekuongorora Energy Band Band uye urema mukati mezvekushandisa, masayendisiti anogona kuenderera mberi nekudzokorora zvivakwa zvavo zvekushandisa kubva mukuchenesa maitiro ekuchenesa. Sezvo isu tichiramba tichisimbisa zvakavanzika zveTitanium dioxide, zvarinenge zvichishandiswa mukuchinja kwemaindasitiri kunoramba kuri pachena.
