General description

Potassium tetrachloropalladate(II) is a dark brown crystalline solid widely used as a Pd source in the field of catalysis, nanomaterial synthesis, and electronics.

Application

Potassium tetrachloropalladate(II) can be used:
  • As a precursor to synthesize Pd nanoparticles for catalytic degradation of organic pollutants and Pd-GO electrocatalyst in formic acid and ethanol oxidation.
  • To synthesize Pd–Pt alloy nanocrystals (NCs) with hollow structures by a galvanic replacement method with uniform Pd octahedral and cubic NCs as sacrificial templates. The hollow NCs exhibited higher ORR activities.
  • To synthesize immobilized Pd catalysts, a versatile method involves the layer-by-layer deposition of PAA and PEI-Pd(II) on alumina, followed by the reduction of Pd2+. This approach offers several benefits, including the stabilization of particles through the polyelectrolyte matrix, introduction of selectivity, and a significant reduction in undesired isomerization. Expanding the application of polyelectrolyte films holds promise for further enhancing selectivity in hydrogenation and other reactions.
  • To fabricate conductive and porous metal-organic frameworks(MOFs) for gas sensing applications and also to synthesize bimetallic Pd/SnO2 nanoparticles on metal organic framework (MOF) as an electrocatalyst for ethanol oxidation.
  • To prepare rigid macrocyclic pincer catalysts possessing polyaromatic ligands with enhanced catalytic activity.

Features and Benefits

Used in the synthesis of semiconducting metal-containing polymers in which the polypyrrole backbone has a conformational energy minimum and is nearly planar. Reacts with bis(dithiolates) to metal-bis(dithiolates) with applications in laser Q-switch materials, optical CD recording media, bar code material and superconductivity.

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
