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.

Exposure to palladium (Pd) may lead to clinical allergic reactions. With frequent nickel (Ni) exposure and cross-reactivity between Ni and Pd at the T cell recognition level, positive Pd reactions on patch testing are surprisingly uncommon. PdCl(2) is often used

For patch testing, replacement of the commonly used palladium dichloride (PdCl2) by sodium tetrachloropalladate (Na2[PdCl4]) was recently demonstrated to improve test accuracy and show a significant correlation with nickel (Ni), supporting the concept of cross-reactivity between Pd and Ni. A
