Palladium is a silver-white metal with a low melting point and low density that is uncommon and beautiful. Palladium is most commonly employed in catalytic converters in modern technology, but it can also be found in jewelry, dental materials, watch accessories, blood sugar test strips, surgical equipment, and electrical contacts. Palladium metal with functional surfaces provides numerous performance benefits in a number of applications.

Case 1: Improved catalytic performance with polydimethylsiloxane coating
Alfa Chemistry covers Pd/UiO-66, which is a metal-organic framework (MOF) and stabilized palladium nanoparticles, with a thin coating of hydrophobic substance polydimethylsiloxane (PDMS) through chemical vapor deposition (CVD) to make its surface hydrophobic (NPs). The hydrophobic coating aids in the enrichment of hydrophobic substrates and hence interaction with Pd sites, as well as protecting and inhibiting Pd NP aggregation. PDMS-coated Pd/UiO-66 showed dramatically higher catalytic efficiency and recyclability. A variety of Pd-based catalysts can now discriminate between hydrophilic and hydrophobic substrates thanks to PDMS coatings.
