Application

  • Boron Nitride: A Support to Synthesize Stable Pt-Based Catalysts for High-Temperature Oxidative Reactions: This study discusses the use of hydrogen hexachloroiridate(IV) hydrate for stabilizing platinum-based catalysts on boron nitride supports, highlighting its importance in high-temperature catalytic applications (FBA Rahman, W Diao, JM Tengco, 2019).
  • Iridium–Palladium Binary Alloy as a Counter Electrode in Dye-Sensitized Solar Cells: This study investigates the effects of hydrogen hexachloroiridate(IV) hydrate on the properties of iridium-palladium binary alloys used as counter electrodes in solar cells (NAS Aziz, MYA Rahman, AA Umar, 2023).

Features and Benefits

Catalyzes the electrochemical synthesis of polyaniline on the surface of non-noble metal electrodes. Utilized in the formation of iridium-substituted Dawson- and Keggin-type polyoxometallates by refilling the vacant site of the lacunary precursors.

Questions

1–2 of 2 Questions  
  1. 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.

  2. 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
