Palladium nanoparticle incorporation in conjugated microporous polymers by supercritical fluid processing

Palladium nanoparticles have been dispersed uniformly throughout a microporous poly(aryleneethynylene) material by the infusion of a CO2-soluble Pd precursor. The resulting composite has good thermal stability and has potential applications for example in heterogeneous catalysis. The porosity of the polymeric support was maintained after inclusion of the metal and the hydrogen uptake at room temperature was increased with respect to the unloaded porous support
