Palladium Catalysts Based on Nitrogen-Containing Porous Aromatic Frameworks for Hydrogenation of Unsaturated Compounds

Makeeva, D. A. / Kulikov, L. A. / Oskina, E. D. / Uvarov, O. V. / Maximov, A. L. / Karakhanov, E. A.

Amino-containing porous aromatic frameworks, designated as PAF-20–NH₂-pre/post and PAF-30–NH₂-pre/post, were synthesized using a combination of pre- and post-modification, and were then used to prepare a number of Pd catalysts with various metal concentrations. The activity of the catalysts was tested in selective hydrogenation of a series of alkynes and dienes at 60°C and 10 atm hydrogen pressure. The effects of the modification technique and palladium content on the morphology and catalytic activity of nanoparticles were investigated, and the reaction patterns were identified for each substrate type. The reusability of the catalysts over at least six reaction cycles was demonstrated.
