Description

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.
