Allgemeine Beschreibung

Unser Titan(IV)-oxid, Anatas-Nanopulver ist ein feines weißes Pulver, das aus Titandioxid-Nanopartikeln mit einer Partikelgröße von weniger als 25 nm besteht. Anatas ist ein metastabiles Polymorph von TiO2, das weniger hart und weniger dicht ist als das Rutil-Polymorph. Optisch gesehen hat das Anatas-Nanopulver einen niedrigeren Brechungsindex, absorbiert weniger UV-Licht und weist eine höhere photokatalytische Aktivität auf als das Rutil-Polymorph. Daher wird Anatas häufig bei Anwendungen bevorzugt, bei denen photokatalytische Aktivität erwünscht ist, wie z. B. bei selbstreinigenden Oberflächen und Solarzellen.

Anwendung

Titandioxidpaste kann als transparente Beschichtung für selbstreinigendes Glas verwendet werden.[1]Es gibt Berichte über Titandioxid-Acrylat-Nanokomposite mit geringer optischer Streuung.[2] Es wurden Metallkontakte in Solarzellen auf der Basis von Titandioxid und Di-(isothiocyanat)-bis-(2,2′-bipyridyl-4,4′-dicarboxylat)ruthenium(II) untersucht.[3]

Questions

1–10 of 12 Questions  

  1. Is this product hydrophilic or lipophilic? If it exhibits that property, could you please explain the reason behind it?

    1 answer

    1. TiO2 powders are generally considered to be hydrophilic, with anatase polymorphs being more so than rutile. Uncoated TiO2 powders such as this one also have more hydrophilic properties than inorganic- or organic-coated powders. Anatase has a high surface energy, which contributes to its ability to interact favorably with water molecules. This high energy facilitates the adsorption of water, leading to a hydrophilic surface. The presence of surface defects and the formation of hydroxyl groups (–OH) on the anatase surface enhance its affinity for water. The arrangement of Ti and O atoms in the tetragonal crystal structure allows for a more reactive surface compared to other polymorphs like rutile, which may have a more stable but less reactive surface.

      Helpful?

  2. Is this product a high-purity anatase phase TiO2 or Is it possible that the rutile phase is also included?

    1 answer

    1. This is a high purity anatase phase. There should not be rutile phase present.

  3. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  4. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  5. Are the NP silanized? Do they need to be activated by UV for antimicrobial property?

    1 answer

    1. This product is packaged in glass vials and will not be salinized. Titanium (IV) oxide nanopowder has been proved to be the most active photocatalytic semiconductor under ultraviolet radiation. Ultraviolet (UV) light-mediated activation of titanium dioxide (TiO2) cleans the surface microenvironment through photocatalysis.

  6. What possible solvents can be used with Titanium(IV) oxide, anatase - nanopowder?

    1 answer

    1. According to the chemicals encyclopedia published by the Royal Society of Chemistry (13th ed.), titanium (IV) oxide is soluble in hot, concentrated sulfuric acid and hydrofluoric acid. It is insoluble in water, hydrochloric acid, and nitric acid.

  8. What does "Trace Metal Basis" mean?

    1 answer

    1. For this product, the purity is determined by testing total metallic impurities. Our specifications only allow for a maximum of 1000 ppm. On the Certificate of Analysis, you will be able to see which metals were tested and the amount.
