Summary: Catalyst based on palladium nanoparticles and poly(propyleneimine) (PPI) dendrimers immobilized on mesoporous phenol-formaldehyde support was synthesized. Catalytic characteristics were evaluated in the hydrogenation of 1-octyne, 4-octyne, and 1-hexyne. High selectivity for alkenes (up to 99%) was achieved. Synthesized hybrid catalyst can be recycled without a loss of activity and additional regeneration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
