Descrição geral

Titanium(IV) oxide is a chemically inert and non-toxic semiconductormaterial widely used in the field of photovoltaics and environmentalremediation. Thephotocatalytic activity of anatase is superior tothat of other polymorphs of titanium oxide.

Aplicação

Titanium(IV) oxide can be used as a precursor:
  • To synthesize TiO2/ZnO- calcium alginate photocatalyst for removal of copper from aqueous solutions.
  • To fabricate implantable composite bioelectrode for biosensing applications.
It can also be used as a nanoparticle growth initiator for the anodic modification of microbial fuel cells(MFC) to enhance their performance.

Características e benefícios

  • Higher electron mobility
  • Low dielectric constant
  • Lower ability to adsorb oxygen
  • Higher Fermi level
  • High degree of hydroxylation
  • Superior biocompatibility
  • Corrosion resistance

Questions

1–8 of 8 Questions  
  1. 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

  2. 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
