General description

Palladium(II) nitrate dihydrate is a highly reactive compound that is commonly used in catalytic reactions such as the hydrogenation of organic molecules, dehydrogenation of alkanes, and oxidation of alcohols. It is also used in the electrodeposition of palladium on surfaces and as a palladium source in the fabrication of palladium-containing materials.[1]

It is also employed in the fabrication of low-cost solid-state hydrogen storage devices made of three-dimensional (3D) reduced graphene oxide (rGO) and expanded graphite (EG)nanocomposite (NC) decorated with Pd nanoparticles (NPs).[2]

Application

Palladium(II) nitrate dehydrate is used as a reactant for:
  • Doping activated carbon for catalysis[3]
  • Catalytic use of hydroxyapatite (HAP) supported Pd nanoclusters in the hydrolysis of ammonia-borane.[4]

It′s used as catalyst for:
  • Selective hydrogenation of 1-heptyne[5] and napthalene[6]
  • In highly porous coordination polymer MIL-101 support. [7]

It may also be used as a reactant for:
  • Preparation of platinum-palladium/carbon alloy nanocatalysts for methanol-tolerant oxygen reduction reaction in fuel cells[8]
  • Synthesis of Cu-Pd alloy thin films on Ti substrates by co-electrodeposition of Pd and Cu from nitrate-base electrolytic baths[9]
  • Preparation of palladium catalyst supported on vertically aligned multi-walled carbon nanotubes for microwave-assisted Heck reactions of p-iodonitrobenzene with styrene and Et acrylate[10]
  • Preparation of di-phenyl sulfide-modified Pd/TiO2 catalysts for acetylene hydrogenation[11]

Questions

1–2 of 2 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
