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.

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).

Application

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

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

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
  • Synthesis of Cu-Pd alloy thin films on Ti substrates by co-electrodeposition of Pd and Cu from nitrate-base electrolytic baths
  • 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
  • Preparation of di-phenyl sulfide-modified Pd/TiO2 catalysts for acetylene hydrogenation
